Sticky Column Element not working

I’ve got two columns and one of them is way longer than the other. I want the element in the shorter one to be sticky so that when you scroll down it stays right next to the longer column on the left.

But somehow it’s not working. I used to just be able to click sticky top 0 on the div in the column and it would stick but now that’s not working?

nvm! it was caused by ‘overflow hidden’ being turned on in the container that it was in!
