Continuation of #907

[DerGuteWolf]

• I'm reporting a bug, not asking for help
• I'm sure this is a Leaflet.MarkerCluster code issue, not an issue with my own code nor with the framework I'm using (Cordova, Ionic, Angular, React…)
• I've searched through the issues to make sure it's not yet reported

---

Unfortunatly my fix #909 for #907 was not complete, the recursive call in getAllChildMarkers needs to receive the new ignoreDraggedMarker Parameter.

How to reproduce

• Leaflet version I'm using: 1.5.1
• Leaflet.MarkerCluster version I'm using: 1.4.1
• Leaflet.MarkerCluster.Freezable version I'm using: 1.0.0
• Browser (with version) I'm using: Chrome
• OS/Platform (with version) I'm using: Windows

What behaviour I'm expecting and which behaviour I'm seeing

run Fiddle, click on one of the bigger clusters (which will be a "multi-level" cluster thanks to the freeze), drag one marker from this cluster over another cluster:
Expected: Dragged marker still visible at mouse cursor
Seeing: Dragger marker disappears

Minimal example reproducing the issue

https://jsfiddle.net/7b4xzprd/1/

• this example is as simple as possible
• this example does not rely on any third party code

@DerGuteWolf thanks for the issue and fix. but could u help me reproduce this issue? I tried in fiddle https://jsfiddle.net/7b4xzprd/1/ and the dragger marker did disappear, but when I try on local as well as on https://jsfiddle.net/7b4xzprd/show it seems the dragger marker is working as expected.

Hi @ykzeng ,

thanks for caring for the repo and merging my fix.

In your fiddle your are not freezing the cluster situation with

mcg.freezeAtZoom(11);

(this uses https://github.com/ghybs/Leaflet.MarkerCluster.Freezable).

The problem arises when the clusters are frozen and there is a cluster which when unfreezed and clicked on would result in clusters and not individual markers (ie a "multi-level" cluster).

Regards,
Wolfgang

@DerGuteWolf hi Wolfgang, thanks for the comment. I was just able to reproduce the issue with freezing function and the fix works good. I will catch up on some other fixes and PRs and expect to have a new version soon with this fix.

And thanks for your nice words, I appreciate your contributions to the repo and look forward to working on your future PRs :)

Regards,
Vincent
