Selecting an entry inserted the batch bar as a block above the grid, pushing
every row down ~60px — the list jumped under the cursor mid-click. The bar
now renders inside .content-header, to the right of "All items", and the
header reserves its height (min-height) so appearing and disappearing shifts
nothing at all.
