Double-click to move doesn't work on iPad

Yes, from what I can tell that option is unfortunately only about clicking, not tapping.

Double click input not working

I just tried this out (Android phone, Brave browser) and double-click works. However, double-tapping (with your finger on the screen) does not work. You need to actually double-click, with a mouse. Not many people use a mouse on their phone or tablet so it’s kind of a pointless option for mobile devices.
