 Issue 821717  has been merged into this issue.

Let me know if you see any additional flakes after f0c6 landed.

The test failed on https://ci.chromium.org/buildbot/tryserver.chromium.linux/linux_chromium_cfi_rel_ng/426 which I think is past "f0c6" (which I suppose means d42d1308cb2f7a1ca28af8f197524c80579cf0c6 ? I think it might be more common to use the first few letters of the hash instead of the last few, and more than 4 is also needed to avoid collisions)

Those are different tests than the one in the patch in C#11.

Detected 3 new flakes for test/step "MediaRouterIntegrationOneUANoReceiverBrowserTest.ReconnectSession". To see the actual flakes, please visit https://chromium-try-flakes.appspot.com/all_flake_occurrences?key=ahVzfmNocm9taXVtLXRyeS1mbGFrZXNyTAsSBUZsYWtlIkFNZWRpYVJvdXRlckludGVncmF0aW9uT25lVUFOb1JlY2VpdmVyQnJvd3NlclRlc3QuUmVjb25uZWN0U2Vzc2lvbgw. This message was posted automatically by the chromium-try-flakes app. Since flakiness is ongoing, the issue was moved back into Sheriff Bug Queue (unless already there).

The test in c#23 should be disabled.

Here is a summary of what's been disabled.   I will start a doc with the failure output before it's lost.  It's going to take some effort set aside in Q2 to fix all of these, so setting a future milestone.

MediaRouterIntegrationBrowserTest::MANUAL_OpenLocalMediaFileFullscreen
MediaRouterIntegrationBrowserTest::MANUAL_OpenLocalMediaFileInCurrentTab

MediaRouterIntegrationBrowserTest::MANUAL_ReconnectSession
MediaRouterIntegrationBrowserTest::MANUAL_Dialog_RouteCreationTimedOut

MediaRouterIntegrationIncognitoBrowserTest::MANUAL_ReconnectSession

MediaRouterIntegrationOneUABrowserTest::MANUAL_Basic
MediaRouterIntegrationOneUABrowserTest::MANUAL_SendAndOnMessage
MediaRouterIntegrationOneUABrowserTest::MANUAL_ReceiverCloseConnection
MediaRouterIntegrationOneUABrowserTest::MANUAL_ReconnectSession
MediaRouterIntegrationOneUABrowserTest::MANUAL_ReconnectSessionSameTab

MediaRouterIntegrationOneUANoReceiverBrowserTest::MANUAL_Basic
MediaRouterIntegrationOneUANoReceiverBrowserTest::MANUAL_Fail_SendMessage
MediaRouterIntegrationOneUANoReceiverBrowserTest::MANUAL_ReconnectSession

I dumped a bunch of output from the failed builders into this doc (tried to group by root cause).  It seems like we can fix most of the Presentation API tests by handling pending Mojo callbacks better and working around a ChromeOS DCHECK.
