- Search anything
- Select any group of aggregate groups of aggregate groups, e.g. MediaWiki (ignore bug 47919)
- Select a sub-group
- Click "X other groups"
I. Expected: the other groups with search results are shown and can be selected, in order to filter the search results.
II. Observed: the standard group selector is opened with the full list of top groups (and the arrow pointing at the top). Subgroups are not shown, can't be listed from their parent groups and can't be searched by name. If you select your group you're sent back to step (3).
