Summary

In VSCode you can fold entire blocks of code that are indented under a commented out line. I use this everywhere in other languages to organise my code, in PowerShell this simply does not work.

Today, I set out to find out why. Turns out the PowerShell extension is interfering, In the following example, only the PowerShell extension is enabled (you can see on the right, all other extensions are greyed out, I made sure to reload after).

At the start, I cannot fold any of the functions under their respective commented out lines, the code folding arrow for the commented out lines will not even show in the gutter.

When I disable the PowerShell extension and reload the window, I can fold both functions under their respective commented out lines.

Trying various configurations of "powershell.codeFolding.enable": false and "powershell.codeFolding.showLastLine": false, did not solve the issue. I am not sure what these lines are for but I did try various true/false settings, did not work.

v2023.6.0

Steps to Reproduce

With the Powershell extension enabled try to fold the function under their respective commented out lines:

#------- Function 1 ------
	function Foo {
		param (
			$Foo
		)
		begin{}
		process{}
		end{}
	}
#------- Function 2 ------
	function Foo {
		param (
			$Foo
		)
		begin{}
		process{}
		end{}
	}

Then disable the extension, reload the window and try the same thing again with the above code, it should work this time around.
