Steps:
Load test case and accessible explorer
Drag object from point target over iframe

Notice that "One Two" and the checkbox are exposed, but not "Three"

Also, if the iframe is increased in size, the bug does not appear.

Attachment: One line patch -- a better check to see if text frame is empty

The problem was really that when the viewing area is small, a new text node
sometimes has a 0x0 frame for the primary frame -- all of the frames with
something in them are pushed to the next line. We were checking the primary
frame's size to see if the text node is empty.

Is there a reason this isn't just calling IsEmpty() on the frame?  That should
give the right answer, I would think...

Attachment: Use IsEmpty() which allows us to remove our own hack which checks for empty text frames
