Steps to reproduce:
1. Visit the Beta Cluster: https://en.wikipedia.beta.wmflabs.org/
2. Log in (if you are not already)
3. Ensure the `Use Legacy Vector` setting is disabled within [Special:Preferences#mw-prefsection-rendering](https://en.wikipedia.beta.wmflabs.org/wiki/Special:Preferences#mw-prefsection-rendering)
4. Visit a page within the main namespace, like [Cats](https://en.wikipedia.beta.wmflabs.org/wiki/Cats)
5. Ensure your page is at least 1200px wide
6. Scroll the page down
7. Notice the sticky header appears.
8. Click on the Edit button.
Observed Result: The editor opens at the top of the article, it didn't open at the scroll position where the user clicked on the Edit button,.
Expected Result: The editor should open at the position where the user clicked on the Edit button like it does more intuitively with section editing.
Environment: Beta cluster.
