Steps to reproduce

In practice, catch [System.Management.Automation.RuntimeException] { ... } seems to behave the same as an unqualified catch block.

That is, it catches any exception - even those not derived from System.Management.Automation.RuntimeException

try { throw ([System.ArgumentException] 'foo') }
catch [System.Management.Automation.RuntimeException] { 'What are you doing here? ' }

Expected behavior

The exception thrown should surface as a script-terminating error, because its type isn't derived from System.Management.Automation.RuntimeException, so the catch block should not be entered.

Actual behavior

'What are you doing here?' is output, because the catch block was unexpectedly entered.
