1. Create geomap widget;
2. click severity filter;
3. click on map, hold and drag mouse;
4. observer the severity filter closed;
5. now open severity filter again;
6. press shift+tab to navigate controls till you see highlight on icon inside map and then press shift+tab again, until you can press arrow keys on keyboard and the map scrolls
7. observe that in this case, unlike with mouse click, the severity filter is still open.
I assume that it supposed to work the same way and when map is being scrolled with keyboard, the severity filter should also be closed just like it is using mouse click.
