Describe the bug

When having BetterBags enabled and then opening the mailbox it will no longer show the mailbox window if you somehow try to move the mailbox window. I am running ElvUI and MoveAnything addons. However, this issue only occurs when you have BetterBags enabled.

Steps to reproduce

1. Have BetterBags Enabled
2. Open Mailbox
3. Try to drag the mailbox window
4. Mailbox window now disappears and will no longer show until you reload

BetterBags does not touch, interact with, or even call any API related to anything with the Mailbox. I can't reproduce this. I'm assuming if you disable ElvUI, this goes away for you too.
