Test the three ways to control chat input focus: autoFocusInput config, controller.focusInput(), and persona:focusInput DOM event.
When enabled, the input focuses after the panel opens and the open animation completes (~200ms).
Toggle on, then open the launcher (click the floating button) — the input should auto-focus. For inline, reload the page with the checkbox on.
Programmatically focus the input. Returns false if the launcher panel is closed.
Dispatch a window event to focus a specific instance or all instances.
