browser_sidebar_adopt.js (2736B)

      1 /* This test checks that the SidebarFocused event doesn't fire in adopted
      2 * windows when the sidebar gets opened during window opening, to make sure
      3 * that sidebars don't steal focus from the page in this case (Bug 1394207).
      4 * There's another case not covered here that has the same expected behavior -
      5 * during the initial browser startup - but it would be hard to do with a mochitest. */
