Syntax Highlighting not fully working in TypeScript files when Volar is enabled

[mareszhar]

When I have Volar enabled, some variables in TypeScript lose their colors.

I used the Inspect Editor Tokens And Scopes command to see what was happening, and it seems Volar is causing TypeScript variables to lose their semantic token type. Instead, they are only keeping their more generic textmate scopes, which is causing the loss of nuance in syntax highlighting.

Here you can see how a .ts file looks when Volar is DISABLED:

And here you can see the syntax highlighting issues when Volar is ENABLED:

Notice that in the first screenshot, TypeScript knows that the variable userName is of semantic type parameter. But, in the second screenshot, it only knows the more generic textmate scopes. This problem is affecting all variables, so TypeScript can no longer distinguish the difference between variables defined with const, let, and arguments.

I have tried disabling Volar's TS Plugin, but it didn't make a difference.

I would be extremely grateful if you could look into this bug.

Thank you ✨!
