So if you follow the video that I posted:
- Moves cursor to #2
- Scrolls to bottom of the list
- Scrolls back to the top of the list
- Moves cursor to the start of #1, prompting line to switch from preview to edit mode (red dots appear)
- Moves cursor to the end of #2
- Moves cursor to the start of #3
- Moves cursor to the start of #1 (more red dots appear)
This is really odd behaviour. Sometimes if you just prompt any line item to switch from preview to edit mode then the whole list becomes a sea of red dots. If you just wait then more dots are added eventually it stops adding them.
I thought that this was linked to this ticket but in creating this test case it seems that it happens to short lists as well.
