Subject: Prevent the selection rectangle from being reduced to 0px
X-Git-Url: https://cloud.milkyroute.net/gitweb/dolphin.git/commitdiff_plain/584574e07d17b6ec2b82882c8c9869f5e8597e4e

Prevent the selection rectangle from being reduced to 0px
width or 0px height, so the selected items can not be accidently
unselected when the rectangle width/height becomes 0px.

BUG: 320897
