WeChat Mini Programs < web-view > component navigation bar return button is invalid

I use the < web-view > component to embed a web page, and when I first enter the page, I can go back to the home page when I click the back button.

Press the top back button again to return to the bottom of the page. You need to press the back button again to return to the home page. The back button is made with a href= "- sharp". Is there any way to return directly to the front page of the page?
