The test failures will be fixed by bug #114483.  Marking this bug as dependent on that one.

infinity() is probably not the right value to return if seekableRanges is not empty, but does not have any valid ranges. Definitely an edge case, but probably worth special casing.

Return a 0 from platformMinTimeSeekable() if -seekableTimeRanges have no valid ranges.
