The following issue is technically not limited to the Beta features tab, but happens with all tabs on the preferences page. However, we typically don't link directly to one of these tabs. BetaFeatures as well as the cog wheel in Page-Previews are very prominent places where this issue becomes visible.
Steps to reproduce:
- Go to any page, e.g. User:Deskana
- Click "Beta" at the top right of the page
- You're taken to the beta features page in your preferences, and the screen is either at the top of the page, or at the start of the Beta section.
- You're taken to the beta features page in your preferences, and the screen scrolls a few times before stopping at the bottom of the page.
Tested in both Chrome and Firefox on Windows 7.
