Issue web-platform-tests#34493 - Adds webkitMaskBox* to a unique test

karlcow · karlcow · commit 1900ae014476 · 2022-06-23T15:19:00.000+09:00
As shown in whatwg/compat#202 there is currently no browsers implementing the mask-border-*, which should be the equivalent. They stand on their own and probably for now deserves a test by themselves.
