Returns / new lines — strange behaviour (Mac App)

### Expected
When hitting return on note with To Do check fields I'd expect to see all lines move.

### Observed
Visually the lines don't move when the note contains check fields, but when typing they catch up. Seems glitchy.

Logout, reinstall, login didn't resolve.

### Reproduced
> 1. Any note with check field, hit return
> 2. no new line appears
> 3. new line appears once typing or adding todo check field.

Mac OSX Sonoma Version 14.3 (23D56)
Simple Note 2.19

Reproduce the issue in Simple Note 2.19 on macOS Sonoma using a note with a To Do check field, then trace the note editing and rendering behavior around Return. Done means the new line is visibly shown immediately after pressing Return, without requiring typing or adding another check field.
