Cursor jumping around in composer / editor text box

not yet. i’ll try reproducing it again first thing in the morning when i get to my desk, and also safe mode. i first noticed it a few days ago when i was editing our moderator guide and thought maybe it was a discoTOC thing, but then i noticed a few more times in other places - seems to only happen when i was editing a previous post or quoting someone, in both mobile and desktop. then today a couple of my users also noted they experienced odd cursor behavior lately in mobile view composer box. it’s like you click/tap to get the cursor in a spot where you want to edit or enter text but then when you actually type, the cursor immediately moves to a different place and the text entered appears in the new location. doesn’t happen with the select and edit feature.
