A usual use case can be a game or an artwork, where the player has to catch a moving/morphing/vanishing/blurring object. Or one uses a filtered element to cover other objects (partly) to prevent events for them in such a game to make it more difficult. If the events are not related to the filtered output, practically one can forget filters for such applications completely and has to solve the problem with a simpler graphical output or some blown up source code to simulate the effect of such filters without filters. For the given example with a shadow, already the name implicates, that no event for the shadow is ok, because the shadow is not the object itself (the naive construction of such 'shadows' by designers or here CSS is always a source of fun for me - it does not contain important properties like scattering, diffraction, light source dimensions etc, but anyway...). In case of a filter the output replaces the object effectively, therefore there is no presentation of the original object anymore. Olaf
