[Bug report] Breaks browser history navigation via keybinding

[amarshall]

Description

1. Visit https://vuepress.vuejs.org/
2. Press Guide → Configuration
3. Press alt← to navigate to the previous page using the standard browser keybinding
4. Expect: to be back on https://vuepress.vuejs.org, as that was the last visited page.
   Actual: now on https://vuepress.vuejs.org/guide/getting-started.html, which I never visited, and the correct browser history is now lost.

Using Firefox on Linux. I only use VuePress as a user of documentation in other projects, I found this issue using docs for a different project, and it occurs in the VuePress docs as well. I briefly tried browsing the source code to find the problematic keybinding, but couldn’t find anything obvious, unfortunately, and the lack of source maps on the official doc page made it difficult to pinpoint the event binding.

Reproduction

https://vuepress.vuejs.org/

Used Package Manager

npm

System Info

The forward and back are set according to sidebar/page nav, which will activate prev and next button at the bottom at the page.

Note: this feature won't spoil your history, only key bindings are added.

Indeed the history is not actually broken, but it appears broken because the keybinding for “go back” has been overloaded to mean something else. I hope that you will consider changing the keybinding to not conflict with default browser behavior as it causes confusion.
