Bug 231256 – ASSERTION FAILED: This HTTPServer does not know how to respond to a request for /popup-after-redirection.html

• Component: New Bugs

The following api-tests are constantly crashing starting on iOS 15 Debug:

TestWebKitAPI.ProcessSwap.NavigatingSameOriginFromCOOPAndCOEPSameOriginToCOOPSameOrigin
TestWebKitAPI.ProcessSwap.NavigatingSameOriginFromCOOPSameOrigin

It appears they all started crashing when we updated our queues from iOS 14 to iOS 15.

I was able to reproduce these assertions on iOS 15-simulator 19A402 Debug ToT, using the following test:

run-api-tests --ios-simulator --debug --verbose TestWebKitAPI.ProcessSwap

This isn't a URL, it's a path.

> Tools/TestWebKitAPI/cocoa/HTTPServer.mm:177
> +    m_requestData->requestMap.add(WTFMove(url), WTFMove(response));

It might be worth asserting that we don't already have this path.  If someone hits that assertion, it's probably a bug in their test.
