[Bug] No syntax highlighting for `.cjs` `.vue` files in the search editor

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.79.2
• OS Version: macOS 13

Steps to Reproduce: .js file has syntax highlighting:

I believe that the syntax highlighting comes from whether you have that language extension installed. Is there syntax highlighting when you open a .vue or .cjs file?

[wenfangdu]

@andreamah .vue highlighting requires an extension and I've installed it, .cjs highlighting is built-in and doesn't require extensions, both are highlighted when you open them but are not highlighted in the search editor.

[andreamah]

Just checked, and it looks like syntax highlighting is dictated using a fixed set of mappings. I could probably add cjs since it's built-in but we only support built-in languages for syntax highlighting for this; sorry about that!

@andreamah You mean even if I installed the syntax highlighting extension for .vue files, they still won't work in the search editor? That seems like a bug.

[andreamah]

You can create a feature request to support non-default syntax highlighting for the search editor and we can put it as a backlog candidate to see whether enough people would want to see it.

Unfortunately, using a fixed list is intentional, as the grammar for the search editor cannot be dynamically changed based on which extensions are installed. We would need to do a fairly large restructuring (integrate search editor highlighting into core) to get this working.
