messages moved from trash back to inbox disappear

I consistently lose emails that I try to move back to the inbox from the trash.

To reproduce this do as follows:

1)From wihtin the mail application on your iPhone go into your inbox.
2)Select an arbitrary message and go into it.
3)Click the trashcan icon on the bottom of the screen to move it to the trash.
4)Go back to your mailbox list and select "trash".
5)Open the message you just trashed
6)Click the icon to move the message to another folder on the bottom of the screen.
7)Select the inbox and watch the animation of the message being moved there.
8)Go back to the mailbox list and select "inbox".
9) get upset because the message is not there, its not anywhere, its been deleted. 😟
