<title>Test for Bug 1386840: non-matching media list doesn't block rendering</title>
<link rel="author" title="Emilio Cobos Álvarez" href="mailto:emilio@crisal.io">
<script src="/resources/testharness.js"></script>

<script>
var t = async_test("Test that <link> doesn't block rendering with non-matching media");
var loadFired = false;
var scriptExecuted = false;
function sheetLoaded() {
loadFired = true;
assert_true(scriptExecuted, "Shouldn't wait for load to execute script");
t.done();
}
</script>
<!--
NOTE(emilio): This can theoretically race if an HTTP packet boundary with a
very long delay came right after the link and before the script. If this
ever becomes a problem, the way to fix this is using document.write() as
explained in bug 1386840 comment 12.
