Status: UNCONFIRMED

(Core :: DOM: Editor, defect, P5)

Description

[Jaroslav Benc]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12

This happens if we set display = "none" and later display = "block" on an iframe with an editable document (design mode). 

Reproducible: Always

Steps to Reproduce:
1. Create a new document with an iframe with an editable document
2. Create couple of buttons so you can show/hide the iframe 
3. Select some text and hide the iframe
4. Show the iframe again and notice that the text is not selected any more
Actual Results:  
document selection range is not restored

Expected Results:  
selection range should be shown (as not focused) 

Selection range shouldn't be destroyed from a different document, iframe should loose focus when clicked outside of the iframe but should keep this range.
