Note that we are supposed to fall back when there is actual HTML in the chart. But I added a fix so it doesn't fall back unless there really are foreignObjects in the SVG.

Hi @aviramga,
When I run a demo: http://jsfiddle.net/BlackLabel/9fhajmbe/ chart is exported to a file. Please let me know which browser (including full number of versions) you have.

Chrome: 67.0.3396.99

Hi @sebastianbochan,

I'm fighting same battle right now...
My chart has yAxis with title like this "my units 10^30"

I tried to add simple snippet into highcharts config and export stopped working:

yAxis:{
    	title:{
      	   useHTML: true,
      	   text: 'my units 10<sup>30</sup>'
      }
},

See working example:
