Let's also update line 928 to continue all requests that we did not find in the map, to avoid stalling requests that did not have frameId for some reason.

I canceled them instead of continuing, to avoid accidentally purchasing items via requests that were supposed to be intercepted.

I tried to make a test to repro this by sending hundreds of requests from a frame with redirects, and while they were inflight removing the frame, but I couldn't get it to happen. However the user stack trace is pretty strong evidence that sometimes network requests come in for frames that have been detached. If its a redirect, I get the frame from the first request. Otherwise the request is silently swallowed instead of crashing with unhandled promise rejection.
Fixes #6144.
