Issue Summary

Users can select several items in the backlog using shortcut keys: CTRL+Click and SHIFT+Click.
As the backlog view does not support multi-select, the selection will be lost when attempting to drag/drop, and only moving a single item will be taken into account.
The users should not be allowed to multi-select as it is confusing and let the users think multi-select is supported while it is actually not.

Steps to Reproduce

1. Go to the backlog
2. Make sure there are multiple records showing on your view
3. Try and multi-select more items from the view using CTRL+Click and SHIFT+Click (for example left click on the first, <shift> + left click on the 2nd, <shift> + left click on the 3rd).

Expected Results

Users are not able to multi-select records in the view as it is not supported for ranking and/or sprint assignment.

Actual Results

Users are able to multi-select but when attempting to drag/drop, only the item immediately under the cursor is actually taken into account/selected

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
