If zooming is disabled, the browser can respond to clicks without a 300ms delay since it doesn't have to wait for a double-click zoom. It seems like the best solution to this problem would be to make a global toggle in settings.

Alternately, you can just require multitouch zoom and get rid of the antiquated notion that you can double-click to zoom.

Double tap to zoom is a standard gesture for mobile Safari, hardly antiquated.

That's true, but given that pinch to zoom is nearly ubiquitous, and given that the double tap gesture requires a 300ms lag before responding to single taps, the Web would arguably be better without it.

I can confirm that working around this issue is horrible. That dastardly 300ms makes quick operation of a mobile app a complete pain in the arse. Constantly having to wait for iOS to catch up with you. It really makes the experience horrible.

But that's how iOS want it. If they made webapps that performant then they'd have trouble imprisoning everyone in the App Store.
