I got this popup when creating hu:Johans Valters. The transparent “backdrop” of the popup (the area I can’t use to click in the textarea due to being covered by a <div> with a positive z-index) is as large as the screenshot (I used the Firefox screenshot tool to create a screenshot that covers exactly that <div>), while the actual popup is unreadably small, without any horizontal scrollbar. I wish I could disable the popup entirely (I’ve never created any articles by translating, and I don’t plan to do so), but at least it should be readable, and it shouldn’t have any extra backdrop oversizing it.
