I was breeding some horses when I noticed, upon checking their tabs, that the layout is being cut off when I'm in windowed mode. Essentially everything that isn't visible upon loading the page (that would require you to scroll sideways) is missing. When I switch to full screen I can see everything that I'm supposed to, likewise if I zoom out enough, but if I switch back, it's gone again.

I did not have this issue before the 'features & fixes' update.
