Test case where unnecessary layout is forced for an offsetHeight query

This shows one case to optimize - change is made in the DOM and then
offsetHeight is queried for an element that is a child of a layout boundary. 
Layout then happens for the entire document even though the changed region has
no influence on the offsetHeight result.
