Today's git master via the nightly Flatpak repo STEPS TO REPRODUCE 1. Type "# header" in the chat bar 2. Delete all the text 3. Type anything else OBSERVED RESULT The text is huge, keeping its old header formatting. EXPECTED RESULT The formatting is reset ADDITIONAL INFORMATION Could be considered an example of Bug 516111, but I thought I'd report it separately in case Bug 516111 isn't considered a problem, since this specific issue is pretty clearly a bug.
