Gmail changed something and emptying Archive folder deleted all mail.

[WNYmathGuy]

NOTE: I called out Gmail specificallly because a Yahoo account of mine didn't have this unexpected result.

Steps to reproduce

1. Open gmail account with rainloop in nextcloud interface.
2. Navigate to the Archive folder.
3. Click the link to clear the folder.

Expected behaviour

Items that were deleted but not expunged would become expunged.

Actual behaviour

All inbox and subfolders contents were permanently deleted. This was confirmed by opening the webmail interface with google.

Little update here, about a day after posting, gMail stopped connecting to Rainloop. It just started working again tonight. I connect with IMAP. The Archive folder is still doing its weird thing. It seems to be all folders except trash.
