The Web Animations Level 1 specification indicates the following for the
`duration` property
of the `OptionalEffectTiming` interface [0]:
> The iteration duration, which is a real number greater than or equal to
zero
> (including positive infinity) representing the time taken to complete a
single
> iteration of the animation effect.
Looking through the Web Animations Level 2 and Scroll-driven Animations Level 1
specifications,
there is no text anywhere that indicates that an infinite duration for a
progress-based animation
would yield an exception. As such, the test expecting `Infinity` for `duration`
to throw is in
error. So we're modifying the relevant test to expect this to be a valid value
instead.
Assuming there may have been an intent to restrict the `duration` for
progress-based animations,
the following issue [1] was filed on the Scroll-driven Animations specification.
