I cannot reproduce this on any release channel on any platform. It may be better for you to log this information on our Github for our developers to review.
No. I’m saying that without more actionable information, I am not what we can do about this issue. I said above that you should log this on Github but honestly it will probably be closed due to that same lack of information to go on and a lack of user reports.
Perhaps, the next time this happens, you can note what you were doing at the time that it happened as well as other details like what sites you had opened, what extensions (if any) were running etc. This may make it easier to reproduce or diagnose the issue. This why when you click Open new topic on Community, there is a template for you to fill out in the editor asking for the types of details that help the developers isolate and fix an issue.
