 # test on Dartium, which requires all tests to have a library.
 [ $runtime == dartium || $runtime == drt ]

I think you need to put it under a
[ $compiler == none && ($runtime == drt || $runtime == dartium) ]

otherwise this will also mark it as flaky on chrome linux

 serialization/test/no_library_test: Skip # Expected Failure
+mdv/test/template_element_test: Pass, Fail # Issue 12177
 
 # Skip tests on the VM if the package depends on dart:html
 [ $runtime == vm ]
