More Responsive Tapping on iOS | WebKit

This solution to the mobile tap delay by the WebKit team sounds like what I was hoping for:

Putting touch-action: manipulation; on a clickable element makes WebKit consider touches that begin on the element only for the purposes of panning and pinching to zoom. This means WebKit does not consider double-tap gestures on the element, so single taps are dispatched immediately.

It would be nice to know whether this has been discussed with other browser makers or if it’s another proprietary addition.
