Yeah, the problem is that this still could have some (potentially)
other issues as the codepath used to draw the page is so different
from the codepath used to draw the selection, and thus why I didn't
want to change the behaviour that much as you are proposing now. Then
I went to see how Okular handle selections but then I got sidetracker
(as always)
