I have a D8 site with a theme based on Bootstrap.
I'm using Superfish for the main menu, and all is well - except that the little arrow indicator triangles that show that an item has a submenu aren't showing - but this only happens in Chrome.
They work fine in Safari and Firefox.
The triangles are implemented in an :after pseudo-selector like so:

ul.sf-menu .sf-sub-indicator:after {
  content: "▼";
  left: 0;
  line-height: 1;
  position: absolute;
  text-indent: 0;
  top: 0; 
}

Devtools Console shows no complaints.
Anyone have an idea how to debug this?
