I am NOT able to reproduce it on Chromium Version 87.0.4280.88 (Official Build) snap (64-bit). Kubuntu 20.10.

I don't know why you can reproduce it on Chromium and me not.

However it looks definitively a bug of Firefox and not of the website.

On Ubuntu20.04 64bit: The problem is also reproduced with Chrome 87.0.4280.88: https://youtu.be/VrbnE01kX_I
However,
On Linux Mint 19 cinnamon: I can't reproduce the problem with Nightly86 and Chrome87.

Hi,

Selecting with the keyboard works, only selecting with the mouse is affected.
