When we double click a form submit anchor, and depending on the selected
element before click, the selection range ("document.getSelection()") can
start from a parent of the targeted node. This will send a wrong range
to be used in LinkDialog widget.
The goal of this commit is to prevent this behaviour by adjusting the range
if it starts from anchor parent.
Note: the bug only occurred in Firefox.
