Seems unrelated to the PR where the test failed #4616, but didn't seem to fail in neighboring builds, so possibly a flakey test?

[mdh1418]

This test only fails on manually created PRs, hence then neighboring builds from dotnet-maestro didn't fail. #4656 was created to verify that the test fails on manually created PRs and not just #4616. The test failed, and so now #4656 aims to disable the DumpMT Verification step of the test on Alpine to unblock PRs.
