* fix: allow selection within link
fixes: #8391
The glance feature was clashing with the possibility to select text within a link.
To avoid the conflict, glance will only open upon mouseup and only if the mouse hasn't moved since the mouse was pressed.
* remove redundant condition
* register listeners in correct place
* feat: Listen to mouse move only once, b=no-bug, c=common, glance
