Suppress errors in Snapping.js

[tanthammar]

On mouse-over, markers, L.Divicons or sometimes layer groups,
with a tool active,
I get errors in console where this._snapList is undefined.

It originates from events dispatched from Leaflet when tooltips are opened/closed.

This error sometimes breaks Geoman and I have to reload the page to continue.

A simple solution is to check the _snapList property.

This non-breaking change, solves the problem.

Thank you for your contribution but before I will merge this, I need a reproducable example when this happens.

I haven't found a situation where this._snapList can be undefined when _handleSnapLayerRemoval is called. Do you have a custom implementation? Do you use a Framework?

Please describe step by step how I can reproduce this error. And please create a demo: https://jsfiddle.net/wv9hz6ec/

@Falke-Design I do understand that you want me to reproduce the error.
I use TALL-stack. Laravel, Alpine js, Livewire, Tailwind.
The task is too big for me to setup a demo.
I have made a fork where I added the change.
Thank you for replying and for maintaining this awesome tool!
Apologies for not going all the way with reproducing the error for you.
