Anchor link not working properly if same id is present on the page.

[iFlameing]

To Reproduce

1. Create a Page and add a heading tag and copy it.
2. Go to another page and paste the copied heading.
3. On same page create a link which point to firstpage heading.
4. When you click Volto first navigate to that page and then scroll to previous page anchor tag.

Please create a scrollable page to clearly see the issue.

@iFlameing can you provide an estimate how much work a fix would be?
