Question Bank: Item preview in table is detached from item when sorting the table

Reproduce:

• either in "My questions" or a pool: open the preview of an item in the table view
• now change the sorting by clicking on one of the column headers. The preview placement doesn't change and thus gets detached from its original item this way

--> the preview should either move with its item OR should be closed.

The problems also seems to occur after adding new items.
