Bug 1997173 [wpt PR 55748] - Removing out-of-spec throw in blink animation and animation_effect, a=testonly
Automatic update from web-platform-tests
Removing out-of-spec throw in blink animation and animation_effect
Currently animation creation and animation effect updateTiming will
throw an exception if its timeline is a scroll timeline and: when the
iteration duration or count is infinite, when the animation effect's
start or end delay is 'auto'. The throws are not in spec. This change
removes the throws for infinite iteration duration because that case is
handled.
