[BUG] Get-PnPTermGroup : returns all tenant terms groups and not only the connected site collection's ones

[Mathieu-Valmont]

Suddenly the Get-PnPTermGroup cmdlet returns all tenant term groups where it used to only returns the terms groups of the connected site collection.

I'm still working on PowerShell 5.1 and the 1.12.0 version of PnP.
I know this version is not maintained anymore but I don't understand why this change suddenly occured.

OS: Windows

How to reproduce :

1. Connect to a site collection
   Connect-PnPOnline -Url [sitecollection] -clientid $myClientId -clientsecret $myClientSecret
2. Execute Get-PnPTermGroup

Thank you for your help.

The same issue is in latest version (2.12.0) as well :(

I can confirm the same problem with version 2.12.0

It seems like it is related to the #2222

If you use app id/app secret for connection - Get-PnPTermGroup returns unexpected results (seems like it does not use current connection for specific site)

If you use other connection options, for example - Connect-PnPOnline -Url "your site url" -UseWebLogin - it works as expected
