When using the jquery.ui.draggable module loaded by the ResourceLoader ( e.g. in the RevisionSlider or WikiEditor extensions ) it triggers deprecation warnings on the JavaScript console.
This page is using the deprecated ResourceLoader module "jquery.ui.widget". This page is using the deprecated ResourceLoader module "jquery.ui.core". Please use "mediawiki.ui.button" or "oojs-ui" instead.
Any help fixing this is appreciated.
