org.eclipse.elk.nodeLabels.placement values have no effect

Current behavior

Adding the layout option org.eclipse.elk.nodeLabels.placement will always put the node labels above the node, regardless of the used value. None of the possible values (H_LEFT, H_CENTER, H_RIGHT, V_TOP, V_CENTER, V_BOTTOM, INSIDE, OUTSIDE, H_PRIORITY) will have any effect on the label position. Even the value INSIDE will place the label outside of the node.

Expected behavior

Using the layout option 'org.eclipse.elk.nodeLabels.placement': 'H_LEFT' should place the label on the left side of the node.
Using the layout option 'org.eclipse.elk.nodeLabels.placement': 'V_BOTTOM' should place the label on the bottom of the node.
Etc.

Minimal reproduction of the problem with instructions

Code Sandbox

What is the motivation / use case for changing the behavior?

Placing labels to specific sides outside of a node
