TableOfContentsc causes timeout when {{ exists in code block.

[willhaines]

What version of Hugo are you using (hugo version)?

$ hugo version
hugo v0.110.0-e32a493b7826d02763c3b79623952e625402b168+extended linux/amd64 BuildDate=2023-01-17T12:16:09Z VendorInfo=gohugoio

Does this issue reproduce with the latest release?

Yes.

Description

I discovered this while using the geekdocs theme, but as far as I can tell the bug is not specific to that theme.

If your page has:
1. A code block with the sequence {{ somewhere in it
2. That code block is wrapped in a shortcode that renders it to html
3. A table of contents
then, it will cause a timeout and fail to render.

Oddly enough, removing the table of contents from such a page fixes the problem. As does, having the code block not be wrapped in a shortcode.

Error message

How to reproduce

layouts/shortcodes/noop.html

{{ .Inner | $.Page.RenderString }}

layouts/shortcodes/toc.html

{{ .Page.TableOfContents }}

content/posts/my-first-post.md

title: "My First Post"

{{< toc >}}

## this is a heading

{{< noop >}}
```
this is some code
   containing
     {{ sequence
```
{{< /noop >}}

When you include .TableOfContents in a shortcode, it forces the current page to be rendered, which includes the shortcode...

Re-opening.

To be clear:

This should work:

In a shortcode in page "foo":

{{ .Page.TableOfContents }}

Should work.

{{ (site.GetPage "foo" ).TableOfContents }}

Will create an infinite recursion.

What I suspect is creating a infinite recursion above is the noop shortcode with:

{{ .Inner | $.Page.RenderString }}

I'm pretty sure it's not about any {{ in the code block, and I suspect you need to simplify your shortcode setup to make this work.

I can reproduce this as described with v0.100.0 and later, but not with v0.99.1.

Git bisect says 9e904d7 is the first bad commit.
