+ * Eeschema crosshair-mode toolbar button (pcbjam #24)
+ *
+ * The left toolbar has a single "Crosshair modes" group button that should switch the
+ * on-canvas cursor between small / full-window / 45-degree crosshairs. In the WASM/DOM port
+ * the three modes are bundled into one ACTION_GROUP whose only directly-clickable action is
+ * the default (small crosshairs) — already the active mode — and the other two live behind a
+ * long-press palette flyout the DOM toolbar can't show. So clicking the button does nothing.
+ *
+ * The fix (kicad/common/tool/action_toolbar.cpp, ACTION_TOOLBAR::onToolEvent, #ifdef
+ * __EMSCRIPTEN__) makes a click on a grouped button advance to the next action in the group,
+ * so a click cycles small -> full-window -> 45-degree -> small.
+ *
+ * This test fails before the fix (the button's tooltip never advances past "Small
+ * crosshairs" and the canvas never changes) and passes after it.
