Reasking because the solutions here aren't working for me.

Can the double-tap-to-zoom be disabled in the latest Safaris? I'm writing a game with a keyboard; people will hit the same key twice while typing fast. Obviously zooming is not appropriate in such a situation.

I've got

<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no" />

I've got

html, body, * { touch-action: manipulation }

I've got style="touch-action: manipulation" on the keys themselves.

Safari still zooms in iOS 15.

Is this fixable?
