Setting `MergeUnclaimedPreviousCommandResults` without `MergeMyResults` throws ScriptCallDepthException

See original GitHub issue

Steps to reproduce

using namespace System.Management.Automation.Runspaces

$ps = $res = $null
try {
    $ps = [powershell]::Create()
    $null = $ps.AddScript("Write-Error 'test'")
    $cmd = [Command]::new(
        'process { Write-Error -ErrorRecord $_ }',
        <# isScript: #> $true)

    # Works if you uncomment this.
    # $cmd.MergeMyResults('All', 'Output')

    $cmd.MergeUnclaimedPreviousCommandResults = 'Error, Output'
    $null = $ps.Commands.AddCommand($cmd)
    $res = $ps.Invoke()
} finally {
    ($ps)?.Dispose()
}

$res

Expected behavior

No output, and does not throw ScriptCallDepthException.

Actual behavior

After ~10 minutes it throws ScriptCallDepthException.
