leaflet.markercluster.js incompatibility with ui-leaflet-layers

[velteyn]

I try to use this plugin together with leaflet.markercluster.js
but I hit an incompatibility issue:
if you put:
`<script type="text/javascript" src="./node_modules/angular/angular.js" ></script>

<script type="text/javascript" src="./node_modules/leaflet/dist/leaflet.js" /></script> <script type="text/javascript" src="./node_modules/angular-simple-logger/dist/angular-simple-logger.min.js" /></script> <script type="text/javascript" src="./node_modules/leaflet.markercluster/dist/leaflet.markercluster.js" /></script> <script type="text/javascript" src="./node_modules/ui-leaflet/dist/ui-leaflet.js" /></script> <script type="text/javascript" src="./edoz/node_modules/ui-leaflet-layers/dist/ui-leaflet-layers.min.js" /></script>` the plugin stops working
