This reverts commit 549da29af80c9d5b64b4c1bcec40b9c81f471a4f and fixes the
problem without breaking text selection in front of background images.

To reproduce, create a large XShape, put it to the background, set wrap
style to 'through', then add some text, including a hyperlink. Click
should select text, ctrl-click should select the hyperlink, or in case
the text is normal, the shape.
