        animation-timing-function property with a list uses first item for all animations
        https://bugs.webkit.org/show_bug.cgi?id=60303

        When an element has multiple animations that have different timingFunctions,
        the progress of each animation should be calculated using its respective timingFunction.
        But at this point, the timingFunction of the first animation is only used for the
        calculation, regardless of how many animations the element has.

        The code for getting a timingFunction is changed by this patch
        so that the timingFunction of the correct animation searched by its name will be used.
