Problem matcher not clearing problems

[aeschli]

I'm working on hello world extension example that uses esbuild.

I'm struggling to get the problem matchers working.

• clone https://github.com/aeschli/ext-ts-esbuild.git
• install the recommended extensions, in particular 'esbuild Problem Matchers'
• add a extra ) at the end of line 19 of src/extension.ts. Close the editor after making the change.
• run `Terminal> Run Task.. / npm watch
• The error is reported in the terminal, and a problem marker is also created
  
• now revert the change again
• the problem is not removed. Killing the terminal also doesn't help. I need to restart the window

The problem matcher is here and looks, IMO, fine: https://github.com/connor4312/esbuild-problem-matchers/blob/main/package.json#L28

Is there a way to debug a problem matcher?

I think this is a duplicate of #164751. I can try to add some logging during debt week
