fire reorder event on XUL tree when treeview is changed
Now we fire platform show/hide events on XUL tree when tree view is changed. The reality is show/hide events aren't used by AT in general. But they listen for reorder events. It's more expected to use it instead of platform show/hide events. Ideally we should fire hide events for all old tree items and new for new tree items but I afraid of perf issue. Therefore I suggest to fire reorder event only and leave show/hide events issue for future.
I need this for bug 498015 where I'm going to process DOM events after layout. So that mochitest can't rely on TreeViewChanged DOM event anymore.
I think we need a try build here.

Comment on attachment 492988 [details] [diff] [review] patch The patch looks straight-forward, but I'd like to see a try build before I can r+ this one.

The latter. This call initializes the tree view?
