Unfortunately I have no access to an iDevice for the remainder of the week as I'm traveling for work. If anyone can help debug this and perhaps even submit PRs, it would be greatly appreciated!
I believe the input lag may be addressed by setting either width=device-width or user-scalable=no on the viewport, or using the CSS touch-action property.

Same here. Android/FF. But still a bit snappier than Google Maps.
