fix: scroll issue w/ tables + fixed position of dropdown ❗️

[ramiAbdou]

Description ✏️

This PR fixes a bug introduced in #766 where we removed the overflow-auto of the table container (in order to use dropdowns w/ absolute position) but now we can't scroll horizontally either. We reintroduce the overflow-auto but now used fixed positioning for the dropdown with additional JS logic to track the x/y coordinates of the dropdown container.
