Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.0.6) Gecko/2009011913 Firefox/3.0.6

When a blurring input-field is removed from DOM and re-appended into DOM, the focus is not set to the newly selected input-field. And it's possible to get text-highlight in two input-fields simultaneously. 
The bug didn't occur when using the tab-key to move focus to next element, so it's only reproducible by using the mouse. 
It works as expected in Safari 3.2.2, Opera 9.64 and Internet Explorer 6.

Reproducible: Always

Steps to Reproduce:
1. Click into top input-field
2. Click into second input-field
3.
Actual Results:  
Second input-field is not focused

Expected Results:  
Second input-field is focused

Enn, any chance your change will fix this?

Should do. It will notify when content gets removed and blur it (without events as there isn't a frame anymore). The testcase for the focus bug has some tests for element removal.

The testcase here works fine when the bug 178324 patch is applied.

This bug should have been fixed by 178324.
