Example screencast of the image zoom issue

When zooming images on Epiphany (v3.36.1, Fedora 32 GNOME DE, webkitgtk 2.28.2), the zoom percentages don't always match the actual zoom level. Seems to be the case at least with some smaller res images. In the example screencast there is a huge jump between 240% and 300% where the resulting zoom is way beyond 300% and after zooming out the resulting 100% zoom is larger than actual size of the image and to get the real 100% zoom you have to reload the page.


Downstream issue ticket on GNOME gitlab, where it was decided it's a webkit bug: https://gitlab.gnome.org/GNOME/epiphany/-/issues/1182
