auto merge of #5064 : glennw/servo/hide-after-layout, r=pcwalton

Browse source 
Prior to incremental layout, the code would remove the existing
construction result. However, with incremental layout the construction result
is cloned rather than removed. This change ensures that the previous
construction result is cleared when an element's display type
changes to none.
