Patch Changes

• Fix Viewport caption placement (#3484) - During the migration to StyleX the layout of the Viewport caption got broken. Now the caption is once again in its correct place.
• Trim dependencies (#3497) - Removed downshift (because unused) and vendored the few icons from react-feathers. These dependencies are either unmaintained, contain legacy code, or make Timvir depend on such through their transitive dependencies. These changes improve the security posture of the Timvir package.
