17 * The sync style load test (for @import). This is, in a way, also an open bug for
18 * ResourceLoader ("execute js after styles are loaded"), but browsers don't offer a
19 * way to get a callback from when a stylesheet is loaded (that is, including any
20 * `@import` rules inside). To work around this, we'll have a little time loop to check
21 * if the styles apply.
23 * Note: This test originally used new Image() and onerror to get a callback
24 * when the url is loaded, but that is fragile since it doesn't monitor the
25 * same request as the css @import, and Safari 4 has issues with
26 * onerror/onload not being fired at all in weird cases like this.
