It seems to be related to the text-expander popup and the debounced suggestion network request. But I am still unable to reproduce it on my side ... will try to figure out.

If anyone has ideas, also thank you very much for the help.

Tried many many times, then caught a new error:

index.js:431 Uncaught (in promise) IndexSizeError: Failed to execute 'setStart' on 'Range': The offset 28 is larger than the node's length (27).
    at #createCloneRange (index.js:431:1)

Try putting real issue id on your side and then copy-paste those lines into new editor instance

Yep, I have tried, but still very difficult to reproduce. I tried to add a Sleep in the IssueSuggestions, maybe it could make it easier to reproduce.

I think the problem overall is like this:

• The issue suggestion request is debounced
• When the request finishes but the textarea has changed, it causes errors in text-expander

Logically looks a lot like it

Hmm, it looks like related to "multiword", but not the debounce ......... really strange.

It's impossible to completely fix the bug, as a workaround, I think we can do this: Fix issue suggestion bug #33389
