I was able to reproduce this failure at iOS 26 Debug ToT running the test as follows:

run-api-tests --iOS-simulator TestWebKitAPI.KeyboardInputTests.SelectionClipRectsWhenPresentingInputView

We see in the history that this test started failing when we transitioned our testing from iOS 18 to iOS 26. It was a constant pass on 18, and became a constant failure since bringing up testing on iOS26.
