New queue design introduces additional scrollbar at small browser size

Issue Summary

The new queue design introduces an additional scrollbar at small browser height (~570px).

Scrolling through the results causes the inner container to pause, then forces the user to scroll down again to make the outer container scroll.

Steps to Reproduce

1. View a queue that contains enough issues to scroll through.
2. Reduce the browser height until an additional scrollbar is created outside the results window.

Expected Results

A seamless scrolling experience at any browser size - comparable to the Issue Navigator or previous queue experience.

Actual Results

When a user scrolls through the list of work items, they reach the end, but can't see the pagination controls until they move their mouse to the outer scrollbar and scroll again.

This can cause a confusing experience for the users with lower resolutions or have hi-dpi scaling on.

Workaround

End users may be able to mitigate this behaviour by making changes at their OS level. See the following Bug Workaround step for instructions on how to enact this:
