Remove invalidated marker

I have a H.map.Group with a bunch of markers.

If i need to remove a single marker i run:

this.markerGroup.removeObject(marker);

But sometimes in other part of my code i run:

this.markerGroup.removeAll();

So if after i run single marker remove method it throws me an error, because there is no such marker on markerGroup layer because all markers were removed previously.

How can i know the marker is valid and exists on a map so i can remove it correctly?

In Yandex Maps i have isValid method so i can validate marker before making some actions with one:

marker.isValid && markerGroup.remove(marker);

If isValid is true it means the marker has geometry and it is on a map, if false means the marker just exists in memory and not attached to the map.

What is equal functionality in Here maps?

H.map.Marker#getParentGroup() or H.map.Marker#getRootGroup() should work for that case.
