    // by e.g. setting the background to red...

    //   document.body.style.background = "red";

    // ...but that also makes this test trivially fail in 'test-verify' runs

    // per bug 1915025 comment 17 through 19, so let's not do that for now.

    // So for now, we handle this unexpected condition silently/gracefully.

    // I'm leaving this (no-op) if-check in the test in case it's useful

    // for debugging/logging at some point, though.
