Configuration

No response

Current and expected behavior

The value that came from the promise should be ignored like when .return is not called. Also it should not be done until all yielded values are returned.

This was found via angular and angular-cli angular/angular#67053
I was able to create a cutdown in the REPL above.

Possible solution
