+"""Check the redesigned help dock on the real widget, offscreen.
+
+The claim being made is a size claim ("84×64 → 26×26"), so this measures the
+widget instead of trusting the constants, and confirms that nothing the old
+three-button layout could do has gone missing — hiding to the edge just moved
+into the panel's ⋯ menu.
