Current Behavior

The current behaviour for:
Chrome:

• When the user scrolls down and presses and holds the ScrollToTop button, the button jumps all the way to the top
  Firefox:
• When the user scrolls down and presses and holds the ScrollToTop button, the scrolling is held midway during the scroll

Expected Behavior

In Firefox, the button should jump to the top and not be held in place

Steps To Reproduce

1. Open monkeytype in Firefox
2. Open settings and scroll down a good amount
3. Press and hold the scroll to top button

Environment

• OS: Windows 10
• Browser: Firefox
• Browser Version: Version 150.0.3 (64-bit)

Anything else?

I tested this on Windows and Linux and they both yield the same result so its likely a browser issue.
I would like to work on this.

Start by locating the ScrollToTop button and its scroll behavior on the settings page, then reproduce the reported hold action in Firefox and Chrome. Trace the button's scrolling entry point and compare the browser-specific behavior; done means Firefox reaches the top without stopping midway, while Chrome continues to work.
