facing the same issue here in meta:
- I opened a composer, and write the title.
- to take an screenshot for this bug, I changed it from a “new topic” to “a new message”.
- I cancel the topic (i.e. the message) as I couldn’t change it back into a topic,
- I started a new topic.
a warning was shown incorrectly (since I already canceled the message):
now even when I chose to “abandon it”, every 10-20 seconds I got this message:
while there is no other tab.
this only happens if I change from a topic to a message. it seems the cancellation of a massage doesn’t really cancel it.
