multi item drag drop broken

Test in version 4.4.1 and 4.2.6, same broken behavior in both. Anthologize version 0.7.6.

Doing any multi item select while in “Manage Parts”, selecting only a few or all posts (about 400) fails.

1. make the selection.
2. drag and drop “posts” title bar over to “part”
3. items show as being moved, but do not show “edit|preview|remove” buttons, and indication that they aren’t really there.
4. leaving the window and coming back the items are missing.
5. export to pdf, the items are missing

drag and drop of any single item, works as expected, edit buttons appear, export to pdf includes the item.

Tested in Chrome, w and w/o “incognito” and in IE. Same behavior.

This would be a fabulous tool for me, IF this worked. Thanks.
