I am having a problem with leaflet markers. The problem is that when I drag a marker with a lower z-index under another marker with a higher z-index and let it go, it makes another marker. I have a click event that adds a marker to the map when I click it.
This happens in Chrome and Internet Explorer 11. This does not happend in Firefox.
Another problem I noticed was that when I would drag a marker outside the browser window and relase in Firefox, it would mess up things up.
