fix(snapshot): dimensions for blocked element not being applied (#1331)

fix for replay of a blocked element when using 'fast forward' (rrdom)

 - Dimensions were not being properly applied when you seek to a position in the replay. Need to use `setProperty` rather than trying to set the width/height directly
