Seems like when tapping the screen on iOS it causes small jitter for the canvas element

[https://labs.phaser.io/edit.html?src=src\physics\arcade\1000%20world%20bodies.js](https://labs.phaser.io/edit.html?src=src%5Cphysics%5Carcade%5C1000%20world%20bodies.js)

in above example on iOS when tapping would cause the objects to jitter / request animation to stop and teleport the objects a tiny bit?

anybody else have an issue with iOS like this
