I don't know of one off the top of my head. I can't see how it could be a
compatibility requirement.

I think what's happening here in Gecko is that a click on a focusable
element moves focus, and a click on an element's scrollbars counts as a
click on the element. So clicking on the scrollbar of a <textarea> or
contenteditable <div> (or even a <button> containing content with a
scrollbar, if you're mad) moves focus to that element. I think this is
quite reasonable actually.

you must be your servant, and whoever wants to be first must be your
slave — just

life as a ransom for many.” [Matthew 20:25-28]
