**Steps to replicate the issue** (include links if applicable):
* Go to [[https://www.mediawiki.org/wiki/Special:Preferences#mw-prefsection-rendering|Special:Preferences#mw-prefsection-rendering]]
* Click the radio buttons in the Skin section to choose different skins.
**What happens?**:
The skin preferences section show/hide based on the previous selection, to be specific:
* Select Vector 2010 from anything, there's an empty Skin preferences section.
* Switch to another radio button after selecting Vector 2010, there is no Skin preferences section at all, even though Vector 2022 has a limited width mode option.
* Switch to selecting Vector 2022 from any option that isn't Vector 2010, both checkboxes are visible.
**What should have happened instead?**:
The skin preferences section show/hide based on the current selection.
