docs.rsshub.app is showing desktop site in Firefox Preview

[ksy36]

Involved route

Visit https://docs.rsshub.app/ in Firefox Preview or in Responsive design mode in Firefox desktop

What is expected?

The mobile version of the site is shown

What is actually happening?

Site loads as mobile at first, but switches to desktop within a second

Additional info (logs errors etc)

We've diagnosed the issue and looks like this is happening due to viewport tag being removed. More information can be found in this comment webcompat/web-bugs#52296 (comment)

This issue seems to relate to an upstream implementation by VuePress:

https://github.com/vuejs/vuepress/blob/01cd096307b55c920f6eb2eb1af9e0f8f2b153ac/packages/%40vuepress/core/lib/client/root-mixins/updateMeta.js#L62

It looks like the current headers are not kept. Further investigation required.

I have successfully reproduced this issue and reporting to the upstream.

Thank you for letting us know lol.
