--- Comment #5 from Joseph Pecoraro <joepeck at webkit.org> ---
Searching WebCore's User Agent Stylesheets, I see the following cases of multiple pseudo-element selectors.

$ find . | ack '\.css$' | xargs ack '::[^ ]+::'
Modules/mediacontrols/mediaControlsApple.css
356:video::-webkit-media-controls-volume-slider::-webkit-slider-thumb,
357:audio::-webkit-media-controls-volume-slider::-webkit-slider-thumb {
559:video::-webkit-media-controls-timeline::-webkit-slider-thumb,
560:audio::-webkit-media-controls-timeline::-webkit-slider-thumb {

Modules/mediacontrols/mediaControlsBase.css
245:video::-webkit-media-controls-volume-slider::-webkit-slider-thumb,
246:audio::-webkit-media-controls-volume-slider::-webkit-slider-thumb {
264:video::-webkit-media-controls-volume-slider::-webkit-slider-thumb::-webkit-slider-thumb:active,
265:video::-webkit-media-controls-volume-slider::-webkit-slider-thumb:active::-webkit-slider-thumb,
266:audio::-webkit-media-controls-volume-slider::-webkit-slider-thumb::-webkit-slider-thumb:active,
267:audio::-webkit-media-controls-volume-slider::-webkit-slider-thumb:active::-webkit-slider-thumb {
427:video::-webkit-media-controls-timeline::-webkit-slider-thumb,
428:audio::-webkit-media-controls-timeline::-webkit-slider-thumb {
447:video::-webkit-media-controls-timeline::-webkit-slider-thumb:active,
448:video::-webkit-media-controls-timeline:active::-webkit-slider-thumb,
449:audio::-webkit-media-controls-timeline::-webkit-slider-thumb:active,
450:audio::-webkit-media-controls-timeline:active::-webkit-slider-thumb,
609:video:-webkit-full-screen::-webkit-media-controls-volume-slider::-webkit-slider-thumb {

Modules/mediacontrols/mediaControlsiOS.css
413:audio::-webkit-media-controls-timeline::-webkit-slider-runnable-track,
414:video::-webkit-media-controls-timeline::-webkit-slider-runnable-track {
420:video::-webkit-media-controls-timeline::-webkit-slider-thumb,
421:audio::-webkit-media-controls-timeline::-webkit-slider-thumb {
434:video::-webkit-media-controls-timeline::-webkit-slider-thumb:active,
435:audio::-webkit-media-controls-timeline::-webkit-slider-thumb:active {
439:audio::-webkit-media-controls-timeline::-webkit-slider-thumb {

Maybe these work in some other way? Either way they may need to be sanity checked to make sure they are still working.
