I am trying to add a SVG element next to the form labels with absolute position. When there is a scroll I am listening to scroll event and updating the position of the SVG. When smooth scrolling is enabled the SVG tends to bounce over continuous scrolling. This bouncing is observed in macOS Chrome and in FireFox when smooth scrolling is enabled.

In Linux/Windows, this can be reproduced by using smooth scroll smooth scroll chrome extension.
