When you have many invalid selections in an options list control, the popover displays all of the invalid options at once without scrolling. This results in the height of page lengthening past the end of the dashboard, adding additional space at the bottom of the page. We should consider making the invalid selections section scrollable like the suggestions part of the popover.

Steps to reproduce

1. Download flights sample data
2. Open flights dashboard
3. Select at least 80 options in one of the options list controls
4. Narrow the time range down to the last 24 hours
5. Scroll to the bottom of the dashboard to see the extra space at the bottom.
