tap-complete not called for last observable inside zip

Describe the bug

Zip tears down all inner observables when it completes before they can run their tap implementations.
When adding a complete-function to all inner observables of a tap, the observable which will complete last and cause the whole zip to complete will not run their complete function iside their tap operator.

I understand that there are multiple solutions to this issue like using the finalize operator, however people don't expect the complete callback to not be called and it took me a while to figure that out.
I'm not sure if this issues comes up in other inner/outer-observable scenarios.

Expected behavior

The complete-callback inside the tap operator should always be called, regardless of when/how it completes.
In the example below, "2 completed" will not be logged. Expected behaviour would be that it will be logged.

Reproduction code

zip(
  of(1).pipe(tap({ next: n => console.log(`${n} nexted`), complete: _ => console.log("1 completed") })),
  of(2).pipe(tap({ next: n => console.log(`${n} nexted`), complete: _ => console.log("2 completed") }))
).subscribe({next: n => console.log(n), complete: _ => console.log("the end")})

Environment

No response

Additional context

No response

Start by running the reproduction URL or the provided zip/tap example and confirm that the second complete callback is missing. Read the zip and tap operator implementations to trace teardown and completion ordering. Done means the last observable's tap complete callback runs and the existing reproduction behavior is covered by a regression test.
