Comment:

 Okay, now I understand how this is reproduced. Scroll down a post, click
 somewhere, then scroll up far enough until the cursor is out of the
 screen. Then start hitting special keys that *shouldn't* cause it to
 scroll back to the cursor.

 This isn't just pagedown/pageup. It's also all modifier keys, including
 Windows/Mac (cmd) keys, function keys, etc... Basically, everything in
 [29535], just not being DRY about it.
