Support Hiding Rows #87

I am trying to implement a filter/incremental search, but I am running into issues with updating the view, especially with large lists (1,000-10,000). I've tried attaching updateSize to the on-input event, but it's still problematic. When I filter everything but the last element, even manual calls using a dedicated updateSize button do not work.

I'm just guessing how you would go about this, but perhaps you could attach an observer to the element's display attribute that calls updateSize.

I created a "refresh" button that calls updateSize and also scrolls to the first matching element. This "fixes" the visual issue but I can't think of a way to detect when there are no elements visible in the viewport figuring out if there is an element that is visible in the list is very inelegant. I'll post a link when I have a working hack, but direct support would be ideal.
