Hey @Mnehmos, Great fix! I can confirm that it works, I left a couple of minor suggestions that might be worth looking into.
Let me know what you think

No async / await: We don't need to await the timeout. We just want to schedule checkAndResolve to run in the future, not pause the entire function. setTimeout does this perfectly on its own. No if Statement: The confusing if statement is gone. We are no longer checking the return value because we don't need to do anything with it in this specific spot. The primary purpose here is just to trigger the check. Clear Intent: The corrected code is much clearer. Its only job is to kick off the checkAndResolve function after 100ms. This acts as a simple, manual trigger to supplement the main onDidChangeTabGroups event listener, which is the more robust part of the fix.

Description
This pull request re-implements the changes from the original PR #4385.
The primary change is a fix for a race condition in the
DiffViewProviderthat could prevent the diff editor from opening reliably. The previous implementation usedonDidChangeActiveTextEditor, which was not always triggered correctly. This has been replaced with a more robust approach that listens foronDidChangeTabGroupsand polls for the diff tab's existence, ensuring the editor is resolved correctly even on slower systems.All debugging
console.logstatements and a superfluous test file have been removed from the original changes.Test Procedure
