Emphasis class not working on headings

[leeaston]

Applying an emphasis class, such as text-primary, to a heading has no effect - the heading retains it's color. Is this expected? I'm hoping not.

Best wishes

Edit: I've just noticed we're supposed to use a span. Couldn't the emphasis classes be made Important to over come this?

We prefer to avoid !important whenever feasible, to make overriding/customization/add-ons easier.
