26079 - Need way to ensure selection is visible

Status: VERIFIED WORKSFORME

(Core :: XUL, defect, P3)

Description

In the sidebar customize dialog you can reorder items with up/down buttons. If 
you have a bunch of panels, it is easy to move the selected item off the bottom 
of the visible view. I see that trees have EnsureRowIsVisible(), but I am unable 
to call this from JavaScript.

This would also come in handy when you add panels in the customize dialog. In 
that case, new panels may be added off the bottom of what is visible.

Hey, alec, didn't you implement this for mail/news?

yep. EnsureElementIsVisible()

This is a dupe of a FIXED bug against me. marking worksforme since I don't feel
like hunting it down.

by the way, that call takes any XUL element in the tree (but not HTML element)
and makes it visible - <treerow>, <treecell>, <treeitem> or even <titledbutton>

Ok, great. I missed that in my first search for it.
