When the Flow inline styles moved to core, we lost the hover behavior for neutral inline quiet anchors, i.e. woith no mw-ui-{progressive|constructive|destructive} colorizing class, just class="mw-ui-quiet". Without a hover behavior, a neutral quiet anchor seems dead.
Neutral quiet anchors used to lighten @colorLightenPercentage on hover, now the generated CSS has separate rules for mw.ui-quiet and mw-ui-quiet:hover but they end up with the same color #666666 (@colorTextLight).
Also, quiet anchors get a dotted outline on click because they don't have outline: none on focus and active.
This would be easier to notice if the generated KSS at http://tools.wmflabs.org/styleguide/desktop/section-6.html had a sample showing <a class="mw-ui-quiet">Neutral (plain)</a>. The way the KSS is set up mw-ui-quiet is a modifier of a regular link.
OR...
Maybe we don't need to support .mw-ui-quiet on its own, and all quiet links must pick a color class. May Galloway has asked for some quiet links to be gray on hover, but currently Flow's Reply • Edit • Thank inline links are all colored..
