Steps to reproduce

  1. Create a file with a few checklist items, e.g.:
## To Do
- [ ] item 1
- [ ] item 2
- [x] item 3
- [ ] item 4
  
## Done
- [x] item 5
- [x] item 6
  1. Select one or more items with the trailing newlines

  2. Try to move the selected item below or above

Did you follow the troubleshooting guide?

Yes

Expected result

I can move the items freely, e.g. group the checked items together.

Actual result

You can’t drop text to the left of the checkboxes (cursor: not-allowed):

You can only drop text between the checkbox and the item to the right of it, but it breaks checkboxes:

If you try to drop text to the left of a checkbox too hard, you can break stuff (the screen below shouldn’t be possible at all):

Additional information

In the legacy edit mode (not live preview) everything works fine.

Moreover, if you manage to force a part of the target zone to be shown as text (e.g. with extra cursors), you can drop stuff there successfully:

I think that the same kind of problem might arise in other cases when a part of the line is converted to non-text, like bulleted list items, images, etc.

A simple way to address the problem might be this: when dragging text around, display drop targets (i.e. the lines under the cursor) as plain text, so the text can be freely dropped to any part of the line.
