Expected Behavior

If a modal extends past the window, I would expect it to scroll.

Current Behavior

If a modal extends past the window, you cannot scroll down or see the content past the viewport.

Possible Solution

In _modal.scss:

   // Modal adjustments

   .modal {
     z-index: $zindex-modal;
+     max-height: 100vh;
+    overflow-x: scroll;
   }
