Copying from most toggle dialogs gives rather unexpected results:

• Layer: "node 123" when node 123 is selected
• Properties: "node 123" when node 123 is selected – macOS problem only, see #20759
• Selection: "node 123" when node 123 is selected
• Relation: "node 123" when node 123 is selected
• Command Stack: "javax.swing.JLabel..."
• Styles: the entire parsed MapCSS for "JOSM default (MapCSS)"
• Authors: OK
• Changesets: "Changeset 123" OK
• Notes: "Note 123: text" OK
