Automatic update from web-platform-tests [@property] Mark for recalc when removing declarations I forgot to notify StyleEngine when the property registry changes due to declarations being cleared. This meant removals would not take effect correctly/predictably. Since CSS.registerProperty / @property use the pattern of static methods on PropertyRegistration to do some work + notifying StyleEngine, we can follow the same pattern for this case. Also rename CustomPropertyRegistered to PropertyRegistryChanged.
