Research direction
Reproduce the issue by opening the supplied TypeScript example in VS Code with extensions disabled, then inspect the repository's TypeScript TextMate grammar files to trace the multiline angle-bracket assertion. Done means syntax highlighting resumes correctly after the assertion, including the following if statements and string literal.
Written by the indexing model from the issue text.
Description
Does this issue occur when all extensions are disabled?: Yes
- VS Code Version: Version: 1.78.2 (Universal)
- OS Version: macOS 13.4
Steps to Reproduce:
- past the following code into a file which has TypeScript set as the language
const req: { query: Record<string, unknown> } = { query: {id1: 'foo', id: 'bar'} };
const { id1, id2 } = <
{
id1: string;
id2: string;
}
>req.query;
if (id1) {
throw new Error('syntax highlighting broke');
}
const backToNormal = 'yay';
if (id2) {
throw new Error('syntax highlighting is back');
}
Screenshot was taken on an instance with all extensions disabled.
Notice how the highlighting breaks after the req.query for the following if statement and its contents.
Here is a second screenshot with different theme added. You can see it breaks in the same spot.
