After testing your issue, Bear Version 2.0 (9652) crashed and show all my other notes as empty.
Only if I restart the app without selecting the test note before closing, my other notes aren’t empty anymore.
Piggy-backing on this thread, since my use-case is slightly different. I have two quoted lines in a row. The first one is rendered correctly. The second one is missing its quote bar. This happens whether or not the first line ends in a double-space.
Bullets:
* first item
New line in the first item
* second item
> Quoted line in the second item.
> Another quoted line.
* third item
