The button is enabled when the selected element has its label visible

When a label has been hidden from the toolbar button, this button is disabled.
To make the label visible again we need to use the contextual menu, which is not intuitive.

When the label of the selected element has been hidden, the toolbar should propose a button that shows the label (exactly like the contextual menu).

When several elements are selected, the rule could be to give the preference to "Hide":
- if at least one selected element shows its label -> display "Hide label" button
- if all elements hide their label -> display "Show label" button

This rule could also be applied in the contextual menu : the actual rule is :
- if at least one element shows its label and at least one element hides its label -> display no menu
- if all elements hide their label -> display "Show label" menu
- if all elements show their label -> display "Hide label" menu
