Sort order is lost when unpinning an item

[olizilla]

Describe the bug
While trying to unpin several large CIDs, I found that there is no "unpin all" batch option and that the sort order is lost, so trying to sort your pins to show the largest first and unpin them is a painful experience, see:

Expected behavior

• an unpin option is available in batch action at the bottom when multiple are selected
• unpinning a single item does not re-sort the list.
