[Bri Harris]

I was able to replicate this failure on iOS 16 ToT as follows:

run-api-tests --ios-simulator --root TestWebKitAPI._WKDataTask.Challenge

[Bri Harris]

This test appeared to be passing on commit 262557@main, but failed on 262558@main. Will try to replicate to verify regression point and assign appropriately.
