/**
 * This test checks that unprefixing is enabled for whitelisted domains, and
 * that it's disabled for non-whitelisted domains.
 *
 * We do this using an iframe, in which we load a test file at a test domain,
 * and we have the iframe report back to us (using postMessage) about
 * whether unprefixing is working.
 *
 * High-level overview of the process here:
 *  - First, we tweak prefs to enable unprefixing & enable the test-only
 *    entries in our unprefixing whitelist.
 *  - The rest of this test is driven by the "startNextTest()" method.
 *    This method pops a hostname to test and loads a URL from that host
 *    in the iframe.
 *  - We then listen for test-results from the iframe, using the postMessage
 *    handler in unprefixing_service_utils.js.
 *  - When the iframe indicates that it's done, we call "startNextTest()"
 *    again to pop the next host & load *that* in the iframe.
 *  - When nothing remains to be popped, we're done.
