== Problem statement For performance reasons we should consider removing `-webkit-linear-gradient` properties, left only for Android 4.3 of our support matrix, from our core's 'mediawiki.mixins.less' `horizontal-gradient` and `vertical-gradient` LESS mixins. Android 4.4. stock browser supports unprefixed property.
