If the page is loaded for the first time, the component is normal.

But when I click the sidebar to jump to the page, the component won't work.

It looks more like an issue of one of your components.

If you are sure that this is vuepress's issue, please remove all of your customized components and provide a minimum reproduction repo. Thank you.
