Function push_state 

pub fn push_state(state: &[u8], title: &str, url: &str)

Push a new entry onto the browser’s history stack without triggering a module reload. This is analogous to history.pushState() in web browsers.

• state: Opaque binary data retrievable later via get_state.
• title: Human-readable title for the history entry.
• url: The URL to display in the address bar (relative or absolute). Pass "" to keep the current URL.
