User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:145.0) Gecko/20100101 Firefox/145.0

Steps to reproduce:

On windows 11 in full screen there is a small line on the very top of the application where no clicks are detected. So if i move the cursor to the very top right i cannot close the firefox, also I cannot select tabs in that top (few pixels) line.

Actual results:

I wanted to close the application quickly by snapping the mouse on top/top right and the mouse reached that thin line where no clicks are detected/handled. This is annoying you need to unnecessarily precise mouse movements where you do not expect it!

Expected results:

Like in previous versions if I clicked in the very top I could open tabs or close the app.
