I came here looking for a solution but q-scroll-area didn’t work for me despite trying lots of variations with this component. So I removed q-scroll-area and implemented something like this:

<div style="max-height: 440px; overflow: auto" class="col">
          <div :visible="false" class="fit column">
		  <!-- stuff you put here will be scrollable. You can adjust the max-height depending on your components -->
		 </div>
		</div>
