`[vscode-adapter]` doesn't recognize using statements for individual tests

[iRon7]

In my use case it actually concerns the using module ... statement but the general issue might be simply reproduced with any using statement as using namespace ...:
Taken the following test:

Using namespace System.Collections
Using namespace System.Collections.Generic

Describe 'Describe-Using' {
    Context 'Using' {
        It 'Should use the using statement' {
            'Test' | Should -not -BeOfType [IList]
        }
    }
}

The pester test runs fine when ran completely (e.g. by pressing F5).
But when invoked in individually (right click on the test --> Run Pester Tests), it apparently doesn't recognize the general using statements for the individual tests, and fails the tests:

Thanks for your submission! Tests generally get run via Invoke-Pester (you can see this in the logs and at the terminal when debugging) so not sure what specifically would be occurring that isn't reproducible with normal invoke-pester. I'm at PowerShell Summit all this week but may try to take a look next week.

Thank you for your feedback.

so not sure what specifically would be occurring that isn't reproducible with normal invoke-pester

Good point, it does actually occur with Invoke-Pester but you might have to start a new PowerShell session to see the issue:

invoke-pester .\Using.Tests.ps1
