OperationCanceledException thrown in getSemanticDiagnostics causes typescript IntelliSense issues

Looks like development on the original plugin is dead, and this repo has the same issue.

I don't see a reason we couldn't add a try catch around the relevant code like you suggested to improve this. Feel free to raise a PR if you'd like, otherwise I'll try to look into it when I have some time.

Is there any chance you have a sample repo where this can be reproduced? That would be helpful for testing + verifying the fix.

I don't have a sample repo but you can replicate it easily by just throwing the error here

lit-analyzer/packages/lit-analyzer/src/lib/analyze/lit-analyzer.ts

Line 186 in 3ef7206

this.context.setContextBase({ file, timeout: 7000, throwOnCancellation: true });

                throw new OperationCanceledException();
