Steps to reproduce

Jump to a certain route in the navigation menu in the page, but the active option has not changed. You can only change it by clicking on the navigation menu active. For example, in about, click on the route jump to home routing, the navigation menu font color has not changed

What is Expected?

When clicked back to the home route, the color of home turns blue, and about returns to black

What is actually happening?

The temporary effect is to click the routing navigation menu without changing the color
