Interpolated strings with escaped brace before interpolation get highlighted weirdly.

[teo-tsirpanis]

Consider the following example, taken from a test:

class TestClass {
    string test = $"hello {{{one}}} world {{{two}}}!";
}

This is how it highlights:

The {{ escaped brace does not get highlighted as string, and instead gets treated as a block start. This produces more side-effects when highlighting a file with this pattern.

From what I saw, it belongs to textmate scopes string.quoted.double.cs, meta.interpolation.cs, string.quoted.double.cs, source.cs. Maybe VSCode has trouble recognizing the quoted string inside the interpolation?

Thanks for reporting. This seems to be another case of an open VSCode issue. Please follow microsoft/vscode#238564 for updates.

this is not a dup of microsoft/vscode#238564. that is some race condition with language settings
this is a dup of Dart's other issue microsoft/vscode#209435
C# is misusing "tokenTypes"
should remove it from package.json

"tokenTypes": {
	"meta.interpolation": "other"
}

and instead use the meta.embedded scope in the C# TextMate grammar
change meta.interpolation.cs to meta.embedded.interpolation.cs

Thanks @RedCMD!
