switchMapped dialogs are closing on error

[loxy]

When using a dialog and producing an error in a switchMapped something (like API call), it is closing afterwards. This is some kind of new behavior, as it was not like this in the past as far as I remember.

Why is that happening? And how can I prevent that?

Here an example:

openDialog() {
  this.dialogs
    .open(this.myTemplate, {
      size: 's',
    })
    .pipe(
      switchMap(() => {
        throw new Error('Damn!');
      }),
      // This will not close it
      // switchMap(() => {
      //   return of('Hello!');
      // }),
    )
    .subscribe({
      next: result => console.log('next', result),
      error: result => console.log('error', result),
      complete: () => console.log('complete'),
    });
}

And in template:

<button tuiButton size="m" appearance="outline" (click)="context.$implicit.complete()">
  <span translate>GENERAL.CANCEL</span>
</button>
<button
  tuiButton
  type="button"
  size="m"
  (click)="context.$implicit.next()"
>
  <span translate>GENERAL.DELETE</span>
</button>

This part hasn't change for a very long time. Dialogs are closed once the stream completes. Your error terminates the stream so that is expected.
