Steps to Reproduce

1. Start debugging an module.
2. When calling function in other module the debugger jumps initially into middle of comment-based help of current function instead of called function body.

It happens also in previous stable version of extension (v2022.6.3).

When that happens, can you type list in the extension terminal? See where PowerShell itself thinks we've hit a sequence point?

Oh, it is in the parameter block of the called function so in the correct place, just the view is not updated:

   24:  #>
   25:          [CmdletBinding()]
   26:          [OutputType([Management.Automation.PSCredential])]
   27:          param(
   28:                  [ValidateNotNullOrEmpty()]
   29:*                 [String]$UserName = [Environment]::UserName
   30:          )
   31:
   32:          try {
   33:                  #Get import key file and credential file paths based on user name
   34:                  $files = Get-KBCredentialFilePath -UserName $UserName
   35:
   36:                  #Throw exception when import key file is not found
   37:                  if (-not [IO.File]::Exists($files['KeyFile'])) {throw [IO.FileNotFoundException] ('Import key file not found: "{0}"' -f $files['KeyFile'])}       
   38:
   39:                  #Throw exception when credential file is not found

Talked this over a bit in discord. Looks like we are setting cursor position but not moving to the next file. So either our call to switch to the file is failing or we're hitting a race where we set position and that's canceling the switch? Something like that. Either way definitely our bug.
