feat: added overflow to large context menus

Hi @timonkrebs, please could you open a ticket with a link to a stackblitz example of the problem you are trying to solve. I prefer having discussion in ticket before agreeing on MR.

look at https://stackblitz.com/edit/node-3zvs2i?file=src%2Fstyles.scss now you are able to scroll the context menu if its too large.
