fix(filters): Fix styles for GitLab
!1258 (merged) changed (and actually fixed) load order for GitLab CSS, revealing some minor problems with filters component:
- class
dropdown-item
was applied twice (byfiltered-search-suggestion
&gl-new-dropdown-item
resulting in extra padding - scrollable area of filters missed explicit background, resulting in weird borders, when background is non-white
This MR addresses both of these issues
