30963	Admin list_editable not suitable for multi-user environment.	Leonardo Arroyo	nobody	"Suppose you have a model with a delete flag for soft deleting(or any other data  for that matter). This field is included in list_display and list_editable on the admin.
Whenever the following flow happens, you can lose data:
- Admin loads the model records listing page.
- An end-user deletes some entry while the admin has the page loaded
- Admin modify another record and save it

This will undelete the record, as django will save the fields for all records listed.
This can be a problem especially for sites with high volume of data being edited, I believe a more appropriate behavior would be to save only the data that the user has actively changed.

Is the current behavior the expected behavior?"	Bug	new	contrib.admin	dev	Normal			Ülgen Sarıkavak	Someday/Maybe	0	0	0	0	0	0
