The commands div should not be added to the DOM. The version shown in the
dock is different to the standard version in the block, and is manually
added to the dock panel when it is displayed.

The docked version contains additional actions (e.g. the undock button).

The original version of the dock should ideally remain untouched.

Note: A duplicate delegation was discovered when fixing this issue. This
was previosuly not triggered because the watched Node was removed
before the delegation took effect.
