I've cleared the Performance Impact field so that this will go back for performance triage again. The bug as originally reported was Windows only and, although I don't remember the details now, it seems that I was able to reproduce locally. If it is impacting Android as well then that would likely bump up the performance impact (along with there being multiple users impacted).
