I wouldn't be surprised but you have the new UI in your video which shouldn't contain stale references unless there's some bug upstream in our bundler or downstream in the browser cache.
I'll continue to be skeptical of contenteditable=true just to be safe.
Based on what sox was saying, it sounds like the browser wants to delete whole words and we are doing something that prevents that. We also deployed some fixes an hour ago, so it could still be some cache thing.
Makes sense because it went away after reboot - caching issue?
