Today on mediawiki.org the user preference always underline links is no longer being honored, when using the Vector skin. All links appear without underline (unless hovering them)

This doesn't happen on commons yet, or Wikipedia.

This preference works when the following code is present:

	/* Underline preference */
	.mw-underline-always a {
	  text-decoration: underline;
	}
	.mw-underline-never a {
	  text-decoration: none;
	}
