**Steps to replicate the issue** (include links if applicable):
* with the skin Vector 2022, the sidebar (main menu) is actually hidden by default
* go p.e. [[ https://fr.wikipedia.org/wiki/Syndicat_intercommunal_(France) | here ]], open it manually by clicking on the burger menu, and change article by clicking on a blue link (p.e. this: "Syndicat intercommunal à vocation multiple")
**What happens?**:
* the sidebar collapse again when you change page
**What should have happened instead?**:
* when you unroll it voluntarily, the sidebar should remain visible until you hide it by yourself
**Software version** (skip for WMF-hosted wikis like Wikipedia):

I can reproduce it when I'm logged-out, not when I'm logged-in (Windows 10 Home, Firefox).
