The documentation header hides information when an anchor is navigated in assistant

The "Qt Reference Documentation" header on each page is in the way when clicking a link refering to an anchor.

For example when clicking the paint function in QWidget, the page will be scrolled such as the function signature is at the top of the page. The problem is that information is not visible since the header is over it.

The same problem occurs if I click a method link from the assistant's index.
