129.0.2 (64-bit) on Ubuntu.
In Fullscreen mode, I'm now having a lot of problems with the Back button.
To show the Back button in Fullscreen mode, you hit the cursor to the top of the screen.
The Back button is below the tab bar. So to hit the Back button, you have to move the cursor down.
If you can move the cursor very quickly - and without overshooting - then it's working fine.
But, if you try moving the cursor down very slowly, then all the browser toolbars scroll up, before (or exactly when) the cursor is in position to hit the Back button.
(So, the problem I'm having must be that I'm not moving the cursor quite quickly enough to avoid this bug).
I use the touchpad on my laptop. I can also reproduce the bug using the touchpoint (small joystick pointer in the middle of my keyboard).
