PowerShell: Get-Help does not recognize documentation comments in PS 7.2.3

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

When there are comments adjacent to documentation comments, documentation comments are not recognized by Get-Help. This doesn’t work:

# Regular comment
<#
.SYNOPSIS
My documentation.
#>

When an empty line is added between these comments, Get-Help works correctly. This works:

# Regular comment

<#
.SYNOPSIS
My documentation.
#>

Powershell version: 7.2.3 Windows version: 11 File encoding: UTF8 (no BOM) File endings: LF

For a demo, save the following file as BugDemo.ps1:

# This comment makes the documentation comments below stop being recognized by Get-Help.
# Add an empty line below this comment (in line 3) and Get-Help works well again.
<#
.SYNOPSIS
Says hi.

.DESCRIPTION
Greets you politely.

.PARAMETER name
Your name.
#>
function SayHi
{
  [OutputType([void])]
  param
  (
    [Parameter(mandatory=$true, position=0, valueFromPipeline=$true)]
    [string]
    $name
  )

  Write-Host "Hi, $name! Nice to meet you!"
}
