[FF] Widgets: Caret goes outside of contenteditable on home/end keys

[Marek Lewandowski]

since: 4.3 (didn't check earlier) until major

Firefox exclusive: pressing home/end key can put caret outside widget.

1. open any sample with image2 plugin (i.e. plugins/image2/samples/image2.html)
2. put caret inside first image caption
3. CTRL + a to select all
4. click on remove formatting button
5. press home key

Expected result:
Caret should collapse at the begining of previous selection.

Current result:
Caret goes outside of widget.

additional info:

1. When pressed home it places itself right before figure[class="caption"].

Problem can be reproduced from CKEditor 4.3 beta - it might be present from the very beginning.

Another common TC:

1. open sample with image2 plugin (/samples/plugins/image2/image2.html)
2. in first image widget caption, select Staurn substring:

   Roll out of [Saturn] V on launch pad
   

3. apply bold pressing ctrl+b
4. press home key

Expected result:
Caret should go to beginging of editable content.

Current result:
Caret goes some where into widget internal structure i guess.

additional info:

1. using ctrl+home / ctrl+end key will result with slightly diffrent result
2. i've checked chrome and ie11 - none of them had this issue

It's general widget editables issue, since it can be reproduced i.e. with simplebox plugin.

Another TC for that issue (this time simple box widget) has been described here: ​http://dev.ckeditor.com/ticket/13507#comment:12.

This TC gives smae results for image2 as @m.lewandowski has described.
