Styles are applied inconsistently after toggling dark-mode with the editor open #2209

To Reproduce
- Create a new post
- Add a group block
- Toggle dark-mode
- Add another group block
Expected behavior
The dark (or light) mode styles should be applied consistently across blocks, and should reflect the current state of the mode.
