Back To Top button js conflict with pure css scroll-behaviour: smooth

Hello Support Team,

I am referring to this thread in the forum:
https://generatepress.com/forums/topic/back-to-top-button-conflict-when-active-smooth-scroll-behavior-smooth/
and have the same problem as described there: I would like to use smooth-scroll behavior: smooth to all anchor link on my webpage.
But when I active the smooth-scroll behavior to smooth, the back-to-top button moves very slowly.
Tom mentioned "This seems like a bug" and this should be fixed in GP 3.1.0

Probably I overlooked a solution? I hope it is just possible to deactivate the "Go-to-top"-buttons smooth-scroll behaviour or some other workaround.

Thank you for looking into this,
Best,
Chris
