Putting results of ocgv on command line erases cursor

I may be missing something, but this feels like a bug in GraphicalTools:

I want to define F7 as “Show command history using ocgv”:

$parameters = @{
  Key = 'F7'
  BriefDescription = 'ShowHistoryOcgv'
  LongDescription = 'Show History using Out-ConsoleGridView'
  ScriptBlock = {
    param($key, $arg)   # The arguments are ignored in this example
    $history = Get-History -Count 100 | Out-ConsoleGridView -Title "Select Command" -OutputMode Single
    if (-Not [string]::IsNullOrWhiteSpace($history)){
        [Microsoft.PowerShell.PSConsoleReadLine]::Insert($history)
    }
  }
}
Set-PSReadLineKeyHandler @parameters

If I hit F7 I get, as expected:

I hit ENTER and get:

So, it put the item I selected (ls) on the command line, but nuked my prompt.

(I’ve tested this without posh-git and oh-my-posh in-play and it reproduces, so it’s not related to that).

This may be a psreadline issue? Or I may not have written ShowHistoryOcgv correctly.

But I think it’s related to GraphicalTools because If I change my $history = above to:

$history = Get-History -Count 1

It works as expected.

This works as expected as well:

$history = Get-History -Count 100 | Out-GridView -Title "Select Command" -PassThru

Anyone have any insight?

Just verified the bad behavior described here does not repro on Linux. My little F7 script above works awesome under Ubuntu on WSL!

Not 100% confident this is the root of the problem yet, but WindowsDriver.cs does a Console.Clear() before it ends up calling CreateConsoleScreenBuffer as shown above. Thus, even thought the logic is there to allocate and use a different screen buffer, it clears the existing one.
