[Bug report] Hash is appended when switching page

[Mister-Hope]

E.g. when visiting https://v2.vuepress.vuejs.org/zh/guide/page.html

You will find out that the page loads and changed to https://v2.vuepress.vuejs.org/zh/guide/page.html#路由

While https://v2.vuepress.vuejs.org/zh/guide/configuration.html won't

Problem

The @vuepress/plugin-active-header-links should special treat and understand <h1> tags, unless the first non <h1> heading reaches top, the plugin should remain the url "hash clean"

Possible solution

vuepress-theme-hope@v1 is using a improved plugin @mr-hope/vuepress-plugin-active-hash forked from @vuepress/plugin-active-hash.

See https://vuepress-theme-hope.github.io/guide/get-started/intro/ as a demo, the plugin will try to empty the hash when scrolling to top, that should be the expect behavior.

Edited:

The current behavior fit most situation, becuase the plugin won't try to scroll page if the hash match the first heading.

But it will have problems when a page has a long excerpt:

# Title

A long excerpt with lots of text and paragraph.

.....

## The first h2 is at the bottom of the page.
