TearDown-Attribute is not working with headless-platform for ui-testing using Nunit framework?

[pm-da]

I would like to use the "TearDown" attribute when testing with Nunit. However, the "TearDown" method is never executed, even if I set a breakpoint in it during a running unit test. Is there a reason for this? The attributes “OneTimeSetUp”, “SetUp” and “OneTimeTearDown” work as they should.
