WP core fill: currentColor is blacking out some custom icons

[JiveDig]

The code from core is:

.components-button svg {
  fill: currentColor;
  outline: none;
}

It's forcing my Heroicons to be all black in the picker:

The icons themselves have fill="none".

This is also happening on the front end... hmmm, maybe an issue specific to Heroicons, because FontAwesome isn't doing it.

Okay, so this happens when you set the icon color and the "Apply icon color to fill" setting is automatically enabled. Disabling it fixes the issue. I guess it makes sense to leave it enabled for the default and most icon sets.

Nick, if this all makes sense and you think it should remain is-is, we can close this issue.
