iCloud email bug when selecting "move to" on same folder

This is a pretty big bug if it's actually doing what it appears to do. That said, try the following AT YOUR OWN RISK -- USE AN EMAIL YOU WON'T MIND LOSING FOREVER:

In the OS X Mail Client, find an email in your inbox (that you won't mind losing). Next, right click it, and select the "move to" option and move it to your inbox (basically moving an email to the same folder it already is in will trigger this bug). The email is now gone.

Anyone else seeing the behavior above?
