// Regression test for https://crbug.com/1101828:
// Test that simply setting a flag (without the backing feature) is sufficient
// to consider a flag unexpired. This test checks that by using a flag with the
// expected unexpire name, but wired to a dummy switch rather than the usual
// feature.
//
// This isn't a perfect regression test - that would require two separate
// browser restarts:
// 1) Enable temporary-unexpire-flags-m$M, restart
// 2) Enable the test flag (which is only visible after the previous restart),
//    restart
// 3) Ensure that the test flag got applied at startup
