I have just finished a fix for this issue but I must provide some context. My testing is based on the rich text copying from Bear to GDocs (Chrome), TextEdit (RTF mode), Slack, Pages, and Word.
Word seems to not manage the RTF lists very well or not as the other apps. You can try making a multilevel list in TextEdit and paste it into Word to see the results. I’m aware the above used to work in Word with Bear 2 but I’m not able to have it work for the other apps and Word. This is what concerns me the most about the fix but I have to rely on user feedback. Bear 1 kinda works if you don’t use deep multi-level lists.
Results for other apps are coherent with the original list but some replace the list items (circle, square, dot, …)
GDocs
TextEdit
Pages
Slack
If you want to report other apps to test I’ll be glad to give it a shot.
