Reviewer's Guide by Sourcery

This PR implements support for IsFixedTabHeader layout component by modifying the GoTop component to work with fixed tab headers. The implementation moves the target element logic to the Layout component and passes it to GoTop through a data attribute, removing the need for JavaScript initialization.
