Running MacOS 10.13.5 and Windows 10 in Parallels. Load Highcharts samples from https://www.highcharts.com/maps/demo/color-axis ... the map background is gray and the states only fill in as I mouse over them.
This happens in both MacOS and in Windows. Screenshot is from Highcharts site.
EDIT Per comment I edited to look like this (since I display both charts and maps from same module):
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.1.1.js"></script>

But I get error 16. I assume I should pull all the libs from github but it looks like as well some of the names have changed?
It seems that this bug is already fixed on master branch of Highcharts:
Live demo: https://jsfiddle.net/BlackLabel/teazgj5r/
Fix will be included in the next release of Highmaps.
