IE: Selection collapses when inserting special char

[Frederico Caldeira Knabben]

1. Clear the cache and load the editor.
2. Select any work by double click.
3. Click the "Insert Special Character" button.
4. Click on any character.

Note that the char has been added at the start of the selection, instead of replacing it.

Confirmed with version 3.2.2. Ok with the 3.2.1.

Adding selection lock when opening a dialog and changing order of instruction a bit in specialchars dialog seems to resolve the issue.

[Garry Yao]

Same issue applies to other dialogs including form fields, the problem is that selection range is not correctly figured out at the first time.

[Garry Yao]

It turns out that the selection restoring logic, might normalize the text nodes thus potentially invalidate the locked selection's correctness, proposing here an isolated approach between these two.

I understand that ​6083_2.patch patch is targeted to review ?

[Garry Yao]

This's a fundamental change, give it your review pls, and we need a 3rd involved in.

[Tobiasz Cudnik]

Removing focus from onInsertHtml and onInsertElement will break #6358 again in webkit.

Replying to tobiasz.cudnik:

Removing focus from onInsertHtml and onInsertElement will break #6358 again in webkit.

I don't get #6358 broken after the patch, but anyway the previous patch's impact could be even reduced, propose the new one here.

[Garry Yao]

Fixed with [5962].
