ForeEach-Object Paraellel in PowerShell 7 - Debugging/Breakpoint

We started testing out the features of PS7's parallel option for ForEach-Object items. One of the difficulties we had a hard time overcoming is how is one supposed to debug code (via ISE/VSCode) when setting a breakpoint?

For example, in the below code block I set a breakpoint on the inner Get-ChildItem (gci) and the code never stops but immediately runs to completion.

$a = Get-ChildItem

$a | ForEach-Object -Parallel {
    $b = Get-ChildItem $a -Recurse
    Write-Host $b.count
}
