spy.show() doesn't filter out observables that run in sync

When using spy.show() from the console, observables that run synchronously are not filtered out of the list.

const asyncSub = new AsyncSubject();
asyncSub.next(null);
asyncSub.complete();

asyncSub.pipe(tag('nodelay.1')).subscribe();
asyncSub.pipe(tag('nodelay.2')).subscribe();

asyncSub
	.pipe(
		tag('delay.1'),
		delay(1),
	)
	.subscribe();

asyncSub
	.pipe(
		tag('delay.2'),
		delay(1),
	)
	.subscribe();

I added some sync tests for the graph flushing to rxjs-devtools and they passed. I’ve added the same tests here and they too pass. I’m not going to look further into this because although the graphing implementation is pretty much unchanged, the snapshotting implementation in rxjs-devtools is completely different.

Why is that a problem? It states that they are complete. There will be more advanced querying capabilities in rxjs-devtools, but this is not something that I intend to fix/change here.

Completed subscriptions will continue to be shown until the keptDuration elapses.
