This would not make sense in some situations e.g. for a UA designed to 
play in-store video adverts (which I hate by the way :) ). In general 
the spec does not and should not mandate or constrain UI, although it 
does sometimes make suggestions (in general I am rather against this 
because the people that are good at writing technical specifications are 
rarely the same people who are good at designing UI, so such suggestions 
are often not that great. And UI is an area in which browsers should be 
allowed to compete).
