At least there are two workarounds (although I really hat this strange "new" behavior too):
1. mark a mail, click "move" button on the top bar, there should be a search field wherein you can type some characters and the matching folder(s) will be listed below and can easily be selected.
2. instead of dragging a mail item and moving with the mouse over the collapsed list of folders, just try to move it down besides (right side) the list of folders and when you have reached the desired one, than move back left over the target folder.

I would like to have the possibility to manually reorder all folders, not only personally created ones but also Archiv, Junk, Drafts, Sent and Deleted.
