Modal has fixed with inherited from .card.

As main content of the page grows, sidebar on the left side grows in height and becomes scrollable with body.

If sidebar overflows on Y axis, it becomes a mess and breaks whole functionality as it's supposed to stay always on screen with sticky.

Solution: Actually, there's a solution, we can just set overflow-y to scroll and it becomes scrollable on Y axis if needed.
BUT, we have a problem, as soon as I set overlfow-y to scroll, the button to toggle sidebar gets cut off as it stays half overflowing the sidebar. setting overflow-x to visible doesn't help.

Recreate: Just set overflow-y to scroll and watch sidebar on collapsed mode.
