Using the 'Show Only Selected' Option with Grouped Actors Selected in the Viewport Still Hides the Grouped Actors

When selecting grouped actors within the viewport and attempting to use the 'Show Only Selected' visibility option from the right-click menu, the actors will be hidden. It is only when you select the 'Grouped Actors' icon within the 'World Outliner' can you use the 'Show Only Selected' option correctly.

The expected outcome would be that when selecting the group actors within the viewport and using the 'Show Only Selected' option, the only visible actors remaining are the ones that were part of the selected group(s).

1. Create or Open an existing project with multiple actors in the Viewport.
2. Select the multiple actors and press the Ctrl+G key to Group them together.
3. Now right-click and selected the 'Show Only Selected' option within the 'Visibility' section.
4. Observe how all of the actors are hidden even though selected.
