Description
This seems to happen only when the resized item is the only one on it's row. Resizing it vertically resets them.

As far as I can see this is due to the fix for #600. _updateStyles() is meant to be incremental but that fix flat out deletes all the styles and only recreates the top (item height + 10) rows
