Failing test: Microsoft.CodeAnalysis.Editor.UnitTests.Structure.StructureTaggerTests.CSharpOutliningTagger_RegionIsDefinition

[Pilchie]

Failed here:

https://ci.dot.net/job/dotnet_roslyn/job/dev15.6/job/windows_release_unit64_prtest/175/

But the test results don't actually include the failure.

@CyrusNajmabadi - can you take a look at what might have happened here?

This doesn't seem likely to be a product issue.
