Make css3dObject div scrollable

I have created 2 renderers, a WebGLRenderer and a CSS3DRenderer, where I both load a glb file and create a css3dobject containing a div. The problem is that I want to make this div scrollable, which kind of works. The scrollbar is displayed and can be used to scroll the div, but when you use your mouse to scroll on the page it does not scroll.
I can’t find any tutorials on how to make a css3dobject scrollable, so I am kind of stuck.
I hope you guys can help:)

without more context, it’s difficult to answer your question. However, I have noticed that sometimes there is a ‘pointer-events:none’ css proptery set (on the CSSRenderer canvas?). Maybe that is your problem?
