If a new email arrives in the inbox while a message is being dragged to a folder, Zimbra erroneously moves the next email instead of the selected/being dragged one.

For example, let's say there are 3 emailns in the inbox as E1, E2, E3. Let's say I click E2 and drag it into a sub folder. But before I could drop that email a new mail (E4) arrives in the inbox. Zimbra, in that case, moves E3 to that folder and leaves E2 in the inbox.
