[Plugin: Magic Fields] MF Post draft is saved as normal Post draft if MF all custom fields are empty

All versions of MF have a very annoying and nasty bug (even MF 1.5.2).

If one does not insert any custom fields data or if one has mandatory fields and does not initialize any of them and hits Save as Draft, wp saves the draft as a normal post draft (it goes outside the custom write panel).
In the case of missing mandatory fields it should not save it at all and just point the empty fields.

I guess the solution is either to create mf line in table also for drafts, or block the draft creation.
