Which @angular/* package(s) are the source of the bug?

zone.js

Is this a regression?

No

Description

While working on #50247, I believe we stumbled upon a patching issue with zone.js.

Zone.js only patches the first Promise returned by fetch. The NgZone become stable after and doesn't wait for 2nd Promise (text() or json() or body which returns a ReadableStream).

This is with the plugin zone-fetch-patch imported.
