Horizontal Bracket Matching doesnt seem to be working

I have enabled these settings inside VS code and it works on for instance javascript files but not on 'vic3' files.
The lines that I used in my vs code settings to enable this functionality:
`"editor.guides.bracketPairs": "active",
"editor.guides.bracketPairsHorizontal": true,
"editor.bracketPairColorization.independentColorPoolPerBracketType": true,
`

Reproduce the reported settings in VS Code on a vic3 file and compare the result with a JavaScript file, using the cwtools-vscode extension as the entry point. Trace how the extension identifies vic3 files and handles bracket-related editor behavior; done when horizontal bracket guides work for vic3 files with the listed settings.
