[BUG] scroll to top not changing cursor to cursor-pointer

When hovering over the scroll to top button:

<img width="344" height="270" alt="Image" src="https://github.com/user-attachments/assets/937715e3-6dc4-44bd-85f1-7b688f733dce" />

The cursor stays normal and does not transform to a cursor-pointer (as with e.g. links).
This indicates to the user that this is not clickable, but it is.
