Context:
1) Edit mode
2) Click on anchor edition button of website form submit button
3) Traceback occurs
The "focus" triggered on $editable element in editor's 'getLinkInfo()'
discards user's text selection on submit button, as a result,
'range.create()' method returns null since no selection is found.
Note: the bug only occurred in Chrome.
Note 2: [1] apparently tried to solve the same issue but the fix was not
solving it correctly, at least not in all cases.
