Description

When working in Distraction-Free Mode, the Add Notes option in the Block Toolbar does not display the New Note form or trigger any visible action.

The issue appears to be specific to Distraction-Free Mode — the same functionality works as expected when the mode is turned off. This impacts the usability of the Block Commenting feature, as users are unable to add notes without exiting this mode.

A short video recording has been attached to demonstrate the issue.
