Bug description

Navigation Back to top button doesn't work with instant loading enabled. The button appears normally, can be pressed normally (hover and pressing is correctly colored), but pressing it doesn't navigate you to the top of the page, the position on the page stays the same. Both Firefox and Chrome-based browsers (I have checked Brave on Linux and Chrome on Android) are affected.

I have additionally confirmed that there is no difference between pressing Back to top button on the initially loaded page and the first page loaded using instant loading (navigated using internal links). The position on the page stays the same in both cases.

This happens since version 9.1.1 and it might possibly be related to fixing #5023 via #5032. Version 9.1.0 works fine.
