It looks as though the tests at https://www.w3.org/wiki/TimedText/IMSC1_Implementation_Report#Tests are based on verifying that implementations do indeed present the subtitles as specified. Are those tests still valid and required, or are we saying that this behaviour is canonically correct but that it is reasonable for some presentation implementations to behave differently to accommodate the situation when the image frame is not fully displayed?

Have re-reviewed this and now don't think there's anything in here that would invalidate the tests.
