[Karl Rackler]

Description:
TestWebKitAPI.WKWebViewCloseAllMediaPresentationsInternal.PictureInPicture
TestWebKitAPI.WKWebViewCloseAllMediaPresentations.PictureInPicture

The first flaky timeout I saw on the dashboard was on 9/14/2022 at 254499@main after the upgrade from iOS 15 to iOS16 on the bots.  These are only flaky timeouts on iOS16 using the iPad (9th generation) model.

Reproduction steps:
I can reproduce this on 255006@main ToT.

Command: 
run-api-tests --iterations 15 --ipad-simulator --model 'iPad (9th generation)' TestWebKitAPI.WKWebViewCloseAllMediaPresentations.PictureInPicture
