It may have been fixed or it is flaky because of 100ms timer. 1655438 3 cdumez 2020-05-22 14:24:13 -0700 I have verified that fixing Bug 212279 fixes this too. *** This bug has been marked as a duplicate of bug 212279 *** 398053 2020-04-30 07:38:13 -0700 2020-04-30 07:38:13 -0700 File with a test download download-blob.html text/html 867 henning PGh0bWw+DQo8aGVhZD4NCgk8dGl0bGU+RG93bmxvYWQgQmxvYjwvdGl0bGU+DQoJPHNjcmlwdD4N CgkJZnVuY3Rpb24gZG9Eb3dubG9hZCh3aXRoVGltZXIpIHsNCgkJCXZhciB1cmwgPSB3aW5kb3cu VVJMLmNyZWF0ZU9iamVjdFVSTChuZXcgQmxvYihbIk5hbWUgLEVtYWlsIl0sIHsgdHlwZTogJ2Fw cGxpY2F0aW9uL2NzdicgfSkpOw0KCQkJdmFyIGRvd25sb2FkTGluayA9IGRvY3VtZW50LmNyZWF0 ZUVsZW1lbnQoJ2EnKTsNCgkJCWRvd25sb2FkTGluay5ocmVmID0gdXJsOw0KCQkJZG93bmxvYWRM aW5rLmRvd25sb2FkID0gImRlbW8uY3N2IjsNCgkJCWRvY3VtZW50LmJvZHkuYXBwZW5kQ2hpbGQo ZG93bmxvYWRMaW5rKTsNCgkJCWRvd25sb2FkTGluay5jbGljaygpOw0KDQoJCQlpZiAod2l0aFRp bWVyID09PSB0cnVlKSB7DQoJCQkJc2V0VGltZW91dChmdW5jdGlvbigpIHsNCgkJCQkJd2luZG93 LlVSTC5yZXZva2VPYmplY3RVUkwodXJsKTsNCgkJCQkJZG9jdW1lbnQuYm9keS5yZW1vdmVDaGls ZChkb3dubG9hZExpbmspOw0KCQkJCX0sIDEwMCk7DQoJCQl9DQoJCQllbHNlIHsNCgkJCQl3aW5k b3cuVVJMLnJldm9rZU9iamVjdFVSTCh1cmwpOw0KCQkJCWRvY3VtZW50LmJvZHkucmVtb3ZlQ2hp bGQoZG93bmxvYWRMaW5rKTsNCgkJCX0NCgkJfQ0KPC9zY3JpcHQ+DQo8L2hlYWQ+DQo8Ym9keT4N Cgk8cD48aW5wdXQgdHlwZT0iYnV0dG9uIiB2YWx1ZT0iRG93bmxvYWQiIG9uQ2xpY2s9ImRvRG93 bmxvYWQoZmFsc2UpIiAvPjwvcD4NCgk8cD48aW5wdXQgdHlwZT0iYnV0dG9uIiB2YWx1ZT0iRG93 bmxvYWQgd2l0aCBUaW1lciIgb25DbGljaz0iZG9Eb3dubG9hZCh0cnVlKSIgLz48L3A+DQo8L2Jv ZHk+DQo8L2h0bWw+
