Vscode-powershell: Notebook Mode: The comment block is not recognized as a Markdown block

[mkht]

Well, can I post any feedback on the Notebook mode that Tyler Leonhardt has posted on the PowerShell blog?

Issue Description

The comment block style that our team normally uses doesn't seem to be correctly parsed as a Markdown block in the Nodebook mode.

<# =========================
# Write comment here
============================ #>

I hope this is improved.

That's odd. That should work. Do normal block comments work?

<#
Foo
#>

Hi @TylerLeonhardt
Yes, normal block comments are working fine.

[rjmholt]

What about this one:

<# x
 # Comment
#>

or this one:

<#
 # Comment
x #>

Or

<#
 # Comment
    #>

(Spacing before the end delimiter)

[TylerLeonhardt]

I bet the first case is broken

[rjmholt]

The code indicates that we expect the whole line to be the comment delimiter, rather than just contain it:

Unfortunately, this is not good in all three cases.
Is this an issue specific to my environment? Is everyone OK?

Case 1

Case 2

Case 3

It's a general bug that we'll fix in the next update. For now cells must start with the line <# and end with the line #>

[TylerLeonhardt]

Yep, should be a straightforward fix and you've given us a great test case :)
