Where does one file a Powershell bug?

PowerShell (Core) is open-source, and is on GitHub. You’d file bugs using the Issues tab on the relevant PowerShell repo.

What’s the bug?

Here is the link to the question I ask.

Basically I’m claiming that it shouldn’t matter if the script is invoked via the call operator or powershell.exe -File. Powershell should provide the same parameter data in each case. It does not. See the above question for how to reproduce the bug
