/milestone v1.19 Thanks for opening this! I'll get you on milestone maintainers soon :) Also, was taking a look at this as well and noticed this test was recently :
As noted in , this modified an existing conformance test and made it flaky. Please move the new test out of the conformance test and mark it as flaky until this issue has been resolved.

I can reproduce this problem by the following steps now.
