Cannot click tag labels (on part of the tag without text)

Bug report

Steps to reproduce

In a existing vuepress blog, visit a post that has tags, and click on one of the tag but outside of the text of the tag.

What is expected?

It navigates to the tag page (listing all the posts with the clicked tag).

What is actually happening?

Nothing happens, the link is not followed.

Other relevant information

This UX issue probably comes from the fact that the tag itself is a li in which only the text is a a (with some ::before etc). Having a structure like li>a>span and changing most of the css to apply on a instead of li and on span instead of a should be close to solving the issue.
