User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.8) Gecko/20100723 Ubuntu/10.04 (lucid) Firefox/3.6.8

After successful or canceled "direct" edition of xul tree's element label, up/down arrow keyboard navigation within xul tree is corrupted and focus is passed outside the tree to it's container.

Reproducible: Always

Steps to Reproduce:
Simple test case attached to this report. Run it with real-time xul editor. The same issue exists in xul trees with enabled direct edition.

Having xul tree (placed in the FF sidebar) you can navigate through its elements with keyboard arrows up, down, left and right (the last 2 for open and close tree's container nodes).

1. Edit any tree element node by mouse action, change or not the element's label, confirm or not with enter or esc key.

2. After successfull or canceled edition, navigation within tree with up/down keys is corrupted. Press up or down arrow keys and you will see that in some cases, especially around the edited tree row, the focus is passed outside the tree. In attached test case the focus is passed to the "parent" container - to the tabpanel. Pressing up/down keys again causes navigation through tab panels.
Actual Results:  
Focus is passed outside the tree. Navigation with arrow keys don't work anymore.

Expected Results:  
Navigation within tree should work as it does before edition.

The key to copy link is broken and has been broken since 88. It was not replaced. The function was removed.

Firefox is currently unusable for everyone who used a hotkey to copy link.

This is completely unacceptable.

Since my legitimate bug reports are being removed, I'm leaving comments on other people's bugs.
