Did the test result box disappear before or after you closed this? I would not be surprised if the failures were related to the buildbot failures for the 3.8 merge -- a problem with an external resource. So I suspect you should have rerun, if possible, after some wait. I will trigger another backport.

The test failures were related to buildbot failures, but I'm not sure when the result box disappeared. I thought if I closed the PR and reopen it, then it would trigger the status checks to run again. That's what I've done on my PRs in the past. But, once I closed it, Miss Islington deleted her branch and I wasn't able to re-open it. I didn't know how to rerun without closing the PR. Sorry about the mess.
