Properly removing layer from map

[do-me]

Whats the preferred way to remove the hexbinlayer from the map?
When I call

map.removeLayer(hexLayer);

or

hexLayer.remove()

the hexbins of the current zoom level freeze and remain as an artifact on the map canvas.

I can simply remove it on one zoom level only with d3.selectAll("g").remove() but is this really the 'proper' way?
I run into problems as I'm using geoman to draw polygons. It also uses g elements so everytime I call the above function I remove the polygon as well.
You can try with the standard hexbins jsfiddle.

I managed to access the parent element with $( ".hexbin" ).parent( "g" ).remove() so it behaves the way I want but still it doesn't seem elegant to me.

Additionally I noticed that after adding the layer to leaflet layer control the layer can't be turned off and behaves in the same way.

This is fixed now in v4.4.1. Sorry it took FOREVER to get around to fixing it.
