This sounds like a good quality of implementation feature. Simple implementations of media source may still be useful without this. The spec can suggest implementations might consider implementing something more sophisticated without requiring any particular technique. -- Configure bugmail: https://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
