Pointer not receiving or handling an "out" or "release" event when mobile safari is swiped from the side (for navigation)

[samreid]

The full description is in phetsims/gravity-and-orbits#340. The summary is that when picking up a "touchSnag" object in the sim while also dragging the edge of the browser (for mobile safari forward/back navigation), then dismissing the forward/back navigation by letting go, the node remains "busy" and cannot be interacted with for the rest of the sim runtime, including after reset all.

@ariel-phet can you please review, prioritize and delegate? This is @jonathanolson's area of expertise.

iOS 15 appears to have resolved this issue. Closing

I saw this problem happen again on iOS 14.0.

I also reproduced the problem on iPad 7 running 14.0.1 testing on gravity and orbits 1.2.0-dev.16

@samreid did your reproduction freeze the sim and make it unable to be used? I could follow the steps, but when I when back to the sim, the sim basically reloaded for me on iOS 14, so everything still worked.

[samreid]

I saw the same symptoms as described in phetsims/gravity-and-orbits#340 where the sim was usable except for the slider. The sim did not reload for me.

This strikes me as an edge case not worth pursuing at the moment, deferring.
