Bug 1519893 - Test the alwaysOnTop feature for Windows. r=aklotz
These tests make sure that passing alwaysOnTop as a window feature results in a window with WS_EX_TOPMOST, and also ensures that web content cannot request alwaysOnTop windows. Differential Revision: https://phabricator.services.mozilla.com/D16570 --HG-- extra : moz-landing-system : lando
