Steps to replicate the issue (include links if applicable):

• Go to 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.
