All the modification to document elements in dialog must obey the editor::insertElement rule in order to not break the selection in IE.

The changes lookg good. There is just a "debugger" line that has been left at line 311.

[garry.yao]

Beside the fix, another small change regard L288 of 4117.patch which should be routed into respected conditional block.

[fredck]

This ticket depends on #4119, which needs to be fixed first.

[fredck]

The attempt to remove the link (by emptying the field) is not anymore working after the proposed patch.

[fredck]

With IE only, I'm having an error in the attempt to remove the link by cleaning the link URL field.

[garry.yao]

This lead us to a mistake within selection plugin, fixing it with other parts untouched.

[fredck]

A console.log call has been left at line 343.
