Pester testing an inlinescript of a powershell workflow

Question

I run the following test with Invoke-Pester. The 'function' tests fine but the 'workflow' fails. Is there any way for the test to see the calls within the InlineScript? Thanks.

BeforeAll {
    function TestFunction {
        Write-Host  "Executing function"
        Get-Host
    }

    workflow TestWorkflow {

        InlineScript {
            Write-Host  "Executing inlinescript"            
            Get-Host
        }
    }
}

Describe "Test-Workflow" {
    BeforeAll {
        Mock Get-Host { "Mocked Get-Host" }
    }
    
    Context 'test' {
        It 'workflow' {
            TestWorkflow
            Should -Invoke -Command Get-Host -Exactly 1
        }

        It 'function' {
            TestFunction
            Should -Invoke -Command Get-Host -Exactly 1
        }

    }
}

The test results:

[-] Test-Workflow.test.workflow 1.53s (1.53s|4ms)
 Expected Get-Host to be called 1 times exactly, but was called 0 times
 at Should -Invoke -Command Get-Host -Exactly 1, C:\Test-Workflow.Tests.ps1:25

Mocking is not possible in workflows as they are executed in a separate process by Windows Workflow Foundation. Pester has no control or state in that process.
