Sticky For Tabs Not working?

Hi all,

I’m trying to create a two columns tab (via grid) where the tabs are sticky and you can scroll through the content on the right right column without the tabs moving place. However for some reason, Sticky on tabs is not working:

I’ve made sure to remove the “hidden overflow” from the tabs content, and made the tabs sticky with respect to the body. But still, it won’t function.

Any help is appreciated
