Very frequently seems to disappear in Chrome. I’ve had this happen on mobile and on desktop (Windows 10 PC) and have had multiple people report this happening as well. Five or six confirmations in chrome, and one report of Firefox ESR. It still appears to work, there’s just no visible cursor to determine where you’re supposed to be typing. Default theme for certain.
I can’t consistently reproduce it. It’s kinda random, but I’ve had enough confirmations to report it here.
