WebKit misplaces caret when scrolling text areas via page-up/page-down on windows
1. Type a bunch of text into a text area
2. use page-up or page down to scroll the text area
the text area will scroll, moving the caret, but the caret will be in the exact same position as it was, relative to the borders of the text area. the text will simply scroll underneath it. See Firefox on windows for an example.
The mac version of this bug (which is slightly different):
This is also a problem when document is in edit mode, caret doesn't move when page down/up is pressed as expected in most of the editors.
I'm marking this as a duplicate because the fix for bug 18819 fixed this as well.
