The CSS `filter` property animates discretely if two `filter` values do not have a shared initial list of filter operations, as specified in https://drafts.fxtf.org/filter-effects/#interpolation-of-filters. What's more, the system we use to animate `filter` in the UIProcess relies on `CAPresentationModifier` on macOS and requires a known list of filter operations for initial setup, which falls apart if we are dealing with mis-matching filter lists. As such we must make sure we don't create `AcceleratedEffect` objects that contain `filter` values that will animate discretely.
