applyTo: closedDocuments and a custom owner caused errors to leak/persist

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.67.2
• OS Version: macOS 12.3.1

Steps to Reproduce:

1. Create a tsup project with the following task:

   {
   	"owner": "tsup",
   	"source": "tsup",
   	"applyTo": "closedDocuments",
   	"severity": "error",
   	"pattern":[
   		{
   			"regexp": "^✘\\s+\\[ERROR\\]\\s+(.+)$",
   			"message": 1
   		},
   		{
   			"regexp": "^\\s*$"
   		},
   		{
   			"regexp": "^\\s+(.+):(\\d+):(\\d+):$",
   			"file": 1,
   			"line": 2,
   			"column": 3
   		}
   	],
   	"background": {
   		"beginsPattern": "^CJS Build start$",
   		"endsPattern": "^CJS .* Build success|^CJS Build failed"
   	}
   },
   

2. Introduce a syntax error in a ts file like just typing % in a line.
3. Open/close the file, the error doesn’t disappear on opening the file.
4. The error persists even after fixing the error in the file.

Removing "applyTo": "closedDocuments" makes it work. It appears like applyTo is getting messed up with a custom owner like tsup that isn’t the language of the file or something?

It has to be a syntax error, so just an “s” which is valid syntax but a type checking error won’t trigger a tsup error. I also had to close the file and reopen it to trigger this for some reason.

@meganrogge Can you try again using a % and saving, closing, and reopening the file, after adding it?

Thanks!

I still can’t reproduce with your exact above steps
