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

Write-Error foo 2>$null
$e = $Error[0]

$e | Get-Member -View Extended | Out-Host

'---'

# !! The unexpected decoration happens here.
# !! Ditto with Export-CliXml
$null = $e | ConvertTo-CliXml

$e | Get-Member -View Extended | Out-Host

Expected behavior

Both Get-Member calls should yield the same output.

Actual behavior

The second Get-Member call reveals many additional NoteProperty members, such as ErrorCategory_Activity.

These members are properties created for serializing ErrorRecord instances, but attaching them to the input objects is inappropriate.
