Consider the following (valid) LaTeX:

\documentclass{minimal}
\begin{document}
This is an asdf undefined command
\iffalse
  \iffalse\fi
  \end{enumerate} 
\fi
\end{document}

LaTex complies it cleanly. But texlab reports a mismatched environment at \begin{document}.

If I remove the \iffalse\fi line, then texlab reports no error. So presumably something about a nested \ifflase confuses it...

texlab: update to 5.5.0.
471a37e 
## [5.5.0] - 2023-04-16

### Added

- Allow optionally passing cursor position to `textDocument/build` request for use in forward search after building.
  Previously, the server had to guess the cursor position ([#475](latex-lsp/texlab#475))
- Add experimental `texlab.experimental.citationCommands` setting to allow extending the list of citation commands
  ([#832](latex-lsp/texlab#832))
- Add support for escaping placeholders in build arguments similar to forward search
- Allow configuring completion matching algorithm ([#872](latex-lsp/texlab#872))

### Fixed

- Fix regression introduced in `v5.4.2` involving `texlab.cleanArtifacts` command.

## [5.4.2] - 2023-04-11

### Fixed

- Fix memory leak when editing documents over a long time ([#856](latex-lsp/texlab#856))
- Fix parsing parentheses in file paths ([#874](latex-lsp/texlab#874))

## [5.4.1] - 2023-03-26

### Fixed

- Do not return symbols with empty names (e. g. sections without name) ([#870](latex-lsp/texlab#870))
- Repair `textDocument/formatting` request ([#871](latex-lsp/texlab#871))

## [5.4.0] - 2023-03-12

### Added

- Add experimental settings to allow extending the list of special environments:
  - `texlab.experimental.mathEnvironments`
  - `texlab.experimental.enumEnvironments`
  - `texlab.experimental.verbatimEnvironments`
- Add `texlab.changeEnvironment` workspace command ([#849](latex-lsp/texlab#849))
- Add `texlab.showDependencyGraph` workspace command

### Changed

- Do not show caption or section names in label inlay hints ([#858](latex-lsp/texlab#858))
- Include more user-defined commands in command completion

### Fixed

- Parse nested `\iffalse` blocks correctly ([#853](latex-lsp/texlab#853))
- Parse commands with multi-byte characters correctly ([#857](latex-lsp/texlab#857))
- Fix checking whether a document can be a root file

## [5.3.0] - 2023-02-25

### Added

- Allow filtering `textDocument/documentSymbols` using regular expressions specified via
  `texlab.symbols.allowedPatterns` and `texlab.symbols.ignoredPatterns`
  ([#851](latex-lsp/texlab#851))

### Fixed

- Do not use percent-encoded path when searching for PDF files during forward search
  ([#848](latex-lsp/texlab#848))
- Always return an empty list of code actions instead of returning "method not found" ([#850](latex-lsp/texlab#850))

## [5.2.0] - 2023-01-29

### Added

- Include line numbers in build warnings when available ([#840](latex-lsp/texlab#840))
- Add `none` formatter to `texlab.latexFormatter` and `texlab.bibtexFormatter` options
  to allow disabling formatting ([#846](latex-lsp/texlab#846))

### Fixed

- Concatenate more than two lines of maximum length in build diagnostics ([#842](latex-lsp/texlab#842))
- Apply the correct range of references to labels when renaming ([#841](latex-lsp/texlab#841))
- Use `document` environment to detect root file instead of `\documentclass` ([#845](latex-lsp/texlab#845))

## [5.1.0] - 2023-01-21

### Added

- Allow manually overriding the root directory using a `texlabroot`/`.texlabroot` marker file.
  See the wiki for more information.
  ([#826](latex-lsp/texlab#826), [#838](latex-lsp/texlab#838))

### Deprecated

- Deprecate `texlab.rootDirectory` setting in favor of `.texlabroot` files

### Fixed

- Do not use `.git`, `.chktexrc`, `.latexmkrc` files/directories to determine the root directory
  ([#826](latex-lsp/texlab#826))
- Fix building documents without an explicit root directory ([#837](latex-lsp/texlab#837))

## [5.0.0] - 2022-12-29

### Changed

- _BREAKING_: `texlab.rootDirectory` is now used as the folder path from which the compiler is executed
  relative to the main document. By default it is equal to `"."`. For more information, please visit the wiki.
- Improve performance of completion by a huge margin due to a faster filtering method used internally
- Do not discover project files beyond the provided workspace folders
- Try to guess the root directory by checking for files such as `.latexmkrc` or `Tectonic.toml` if `texlab.rootDirectory` is not set

### Fixed

- Update positions of reported build diagnostics when editing the affected line
- Do not treat links to files as bidirectional by default. This prevents issues where `texlab` ends up compiling the wrong file
  in projects with shared files ([#806](latex-lsp/texlab#806), [#757](latex-lsp/texlab#757), [#679](latex-lsp/texlab#679))
- Fix coverage of directories which need to be watched for changes ([#502](latex-lsp/texlab#502), [#491](latex-lsp/texlab#491))
- Resolve links of the `import` package correctly
- Use `filterText` of completion items when filtering internally ([#829](latex-lsp/texlab#829))

## [4.3.2] - 2022-11-20

### Fixed

- Do not try to run the TeX engine on package files and fail the build instead ([#801](latex-lsp/texlab#801))
- Handle URIs with URL-encoded drive letters on Windows ([#802](latex-lsp/texlab#802))
- Parse BibTeX entries with unbalanced quotes correctly ([#809](latex-lsp/texlab#809))
- Provide completion for more acronym commands ([#813](latex-lsp/texlab#813))
- Fix parsing acronym definitions ([#813](latex-lsp/texlab#813))

## [4.3.1] - 2022-10-22

### Fixed

- Do not crash with a stack overflow when trying to load packages with many internal dependencies ([#793](latex-lsp/texlab#793))
- Normalize drive letters of all document URIs
- Fix parsing commands that take file paths as arguments ([#789](latex-lsp/texlab#789))
- Use the correct working directory and command line arguments when calling `latexindent` ([#645](latex-lsp/texlab#645))
- Fix publishing to CTAN

## [4.3.0] - 2022-09-25

### Added

- Add inlay hints for `\label{...}` ([#753](latex-lsp/texlab#753))

### Fixed

- Improve accuracy of the error locations reported by the TeX engine ([#738](latex-lsp/texlab#738))
- Reduce number of false positive errors reported by `texlab` ([#745](latex-lsp/texlab#745))
