For modern Vector, the preferred way to place an icon beside a link is with a dedicated <span> element instead of a `:before` pseudo-element. This change appends a <span> element with an icon to links created by mw.util.addPortletLink instead of using the `.mw-ui-icon-before` class.

/**
|
|
* Wait for first paint before calling this function. That's its whole purpose.
|
|
*
|
|
* Some CSS animations and transitions are "disabled" by default as a workaround to this old Chrome
|
|
* bug, https://bugs.chromium.org/p/chromium/issues/detail?id=332189, which otherwise causes them to
|
|
* render in their terminal state on page load. By adding the `vector-animations-ready` class to the
|
|
* `html` root element **after** first paint, the animation selectors suddenly match causing the
|
|
* animations to become "enabled" when they will work properly. A similar pattern is used in Minerva
|
|
* (see T234570#5779890, T246419).
|
|
*
|
|
* Example usage in Less:
|
|
*
|
|
* ```less
|
|
* .foo {
|
|
* color: #f00;
|
|
* transform: translateX( -100% );
|
|
* }
|
|
*
|
|
* // This transition will be disabled initially for JavaScript users. It will never be enabled for
|
|
* // non-JavaScript users.
|
|
* .vector-animations-ready .foo {
|
|
* transition: transform 100ms ease-out;
|
|
* }
|
|
* ```

|
|
* @return {void}
