Test Case behavior in STP160 on macOS 13.1

Hi Team,

While trying to find failing tests based on Blink's commit, I came across following test case:

Test Case: https://jsfiddle.net/yr6t9781/show

^ In above, using STP160, if you scroll in the iframe and then scroll within it, it will keep on spewing iframe and test cases within it and at one point, it will start to make tab stutter and slow to interact and if you go to other tab and come back, you will get splash like grey full screen. Please see a video for reference.

In above, Chrome Canary 111 also keep on spawing iframe but till a limit and then it does not.

Just wanted to raise, so this can be fixed.

Thanks!
