I'll test the Technology Preview build!

The exact version of Safari installed is; 13.0.4 (15608.4.9.1.3).

External monitor usage on macOS is sadly very very buggy, and it actually looks like that might be part of the issue here. I'm using a monitor through the USB-C  port with my MacBook Pro folded, so I only have output on the external monitor. When in this mode I can consitently reproduce the issue on all pages using the Fullscreen API.

I can not reproduce this is if I just use the internal screen on the MacBook Pro. If I connect the external monitor again though I can reproduce.

If I unfold the MacBook so that both the internal montitor and the external montior is running, then I can also not reproduce. 

Peculiar... With Chrome or Firefox in "macOS fullscreen" with HTML5 Fullscreen I cannot reproduce, it only happens with Safari. So must be some calculations that are off so that the mouse position isn't correctly matched to the rendered page?
