Actual behavior:
If the user has selected a label, the label-row is highlighted in gray. The label can be selected by left-clicking on a row in the LabelSetWidget. A selected label may be shown as a segmentation with an outline, to mark the active label.
If the user has selected a label but right-clicks on another label, the action will still be performed on the previously selected label (e.g. merging, renaming) - the active label. This does not happen for all actions (e.g. random color, remove).
Expected behavior:
If the user chooses a label-specific action by right-clicking on a label-row to open the context-menu, the chosen action should be performed on the right-clicked (row-selected) label - not on the active label.
