Url to the build Failure:
https://luci-milo.appspot.com/buildbot/chromium.linux/Android Arm64 Builder (dbg)/46528

What is the bug or feature:
The failed targets are available there, but they are not passed over to try-job.

Be aware that Logdog has some performance issue during that time: response time is much longer than normal.
Roberto knows more details in this.
