Issues identified with current LESS code (& after T97631 & T177432):
- circle mixin cares about the specific colors, but repeats general properties/values in every color instead of a shared circle class
- box-sizing
- border-radius: 50%
-
sets margin instead of top/left, which would be in most cases sufficient and overwrite instead of adding another propertyUpdate 2018-04-07: Due to variance in usage, this doesn't make sense in time-budget vs saved output sense. - OOUI ButtonWidget sets opacity on icons, therefore the colors in .mw-rcfilters-ui-filterItemHighlightButton are not rendered correctly
