[BUG] Connect-PnPOnline ignores the WarningAction and WarningPreference parameters when using the a cached token

[b-a0]

Reporting an Issue or Missing Feature

After creating a persisted login token, subsequent calls to Connect-PnPOnline (e.g. to connect to a different context) print a warning:

WARNING: Connecting using token cache. See https://pnp.github.io/powershell/articles/persistedlogin.html for more information.

As it's a warning I thought setting the WarningAction or WarningPreference to SilentlyContinue would suppress this message.

Expected behavior

Expected to see no WARNING after I've set WarningAction or WarningPreference to SilentlyContinue.

Actual behavior

I keep seeing the warning, regardless of my preferred warning action:

Steps to reproduce behavior

Please include complete script or code samples in-line or linked from gists

$WarningPreference='SilentlyContinue'
Connect-PnPOnline -Url https://<tenant>.sharepoint.com -PersistLogin
