Prerequisites

• [X] Write a descriptive title.
• [X] Make sure you are able to repro it on the latest released version
• [X] Search the existing issues.

Steps to reproduce

1. As a test file I have download the MD help file for Get-Help from. https://github.com/MicrosoftDocs/PowerShell-Docs/blob/main/reference/7.2/Microsoft.PowerShell.Core/Get-Help.md
2. In VS Code I have set a break point on new-externalHelp but the important part is in the function GetMamlModelImpl which has a line $model = $p.ParseString($mdText, $parseMode, $_) (1605 in the .PSM1 file for v 0.14.2 )
3. After this line has run examine $model.children[-3].spans[10..14] | ft style,text -wrap

The markdown

The full view of help includes a table of information about the parameters. The table includes the
following fields:

- **Required**. Indicates whether the parameter is required (true) or optional (false).

- **Position**. Indicates whether the parameter is named or positional (numeric). Positional
  parameters must appear in a specified place in the command.

Note in the last line the extras spaces between "positional" and parameters, because the carriage return has been removed but the indent to keep the bullet point together have not.

Expected behavior

The notes part of Get-Help Get-Help -full displays a notes section similar to what is displayed at https://docs.microsoft.com/en-gb/powershell/module/microsoft.powershell.core/get-help?view=powershell-7.2#notes i.e.

Actual behavior

It displays like this
