In the current implementation, idleTimeout will always be thrown even if it didn't time out and Promise.race was resolved. This causes the error Error: Route did not complete loading on every route transition and Chrome Devtools will pause code execution if you have "Pause on exceptions" enabled.

This PR adds resolvePromiseWithTimeout which does the same thing as Promise.race and idleTimeout, but it cancels the rejection when it resolves successfully, in which case the error won't be thrown.

Fixes #21543.
