as asked here in a related issue in this thread now two issues using Browser zoom in 12.1p+ (tested v12.1p_2023-06-12, v13.0p_2023-06-12 under Win10 FF114 no system zoom, FullHD).
For every test I changed the Firefox browser zoom and then reloaded the page. It happens the same way in Edge 114.
90% makes events shorter. 110% (and reloading again) makes events longer. Please see the videos below.
