Broken template literal type highlight without TypeScript Nightly extension

[greentore]

Describe the bug infer T extends ... syntax within template literal types is highlighted incorrectly. It works fine in vanilla VSCode and VSCodium with TypeScript Nightly extension installed from open-vsx.

Please confirm that this problem is VSCodium-specific

• [X] This bug doesn't happen if I use Microsoft's Visual Studio Code. It only happens in VSCodium.

Please confirm that the issue/resolution isn't already documented

• [X] I checked the Docs page and the Troubleshooting page and my issue is not mentioned there.

To Reproduce

type T0 = "100" extends `${infer T extends number}` ? T : never; // 100
type T1 = "100" extends `${infer T extends bigint}` ? T : never; // 100n
type T2 = "true" extends `${infer T extends boolean}` ? T : never; // true

Taken from https://github.com/microsoft/TypeScript/pull/48094

Expected behavior Template literal highlight shouldn't leak beyond the closing tick.

I can't reproduce the issue on Win10 or macOS.

Have you looked into the logs: View/Output/TypeScript?

[greentore]

It looks like my scoop installation is borked. I can reproduce it on 2 computers with fresh profiles, but not if I run a build downloaded from github directly. Sorry for the noise.

[daiyam]

So the issue come from scoop?

[daiyam]

Hum, I've just tried scoop, no issue...

[greentore]

It was caused by vscode.typescript-1.62.3 in my extensions directory. I guess I copied the whole thing from vanilla vscode years ago. Bisect wouldn't find it as codium was treating it as native extension. Sorry again.

That make sense. No problem.
