Adds call to arrangeItems on the searches grid, which otherwise never get layed out properly Turns out the autocomplete searches grid never has its arrangeItems called. I've added it to updateSearchEngineSubtitles, which is called from invalidate, which ends up doing what we want, when we want it. It might be nice to follow up at some point with a more explicit sequence that says: prepare the contents, show the popup and layout the grids, as there's enough indirection and setTimeout-ery going on here that its not very clear.

Comment on attachment 762735 [details] [diff] [review] Adds call to arrangeItems on the searches grid, which otherwise never get layed out properly Issue still reproduces with this patch when at > 100% display sizing.

This is actually the same issue as bug 858388, just horizontal instead of vertical because of the orient direction value of the container. I'll integrate the arrangeItems patch to the work done over there, update its title and dupe this one.
