Select All Descendants in World Outliner Does Not Highlight Everything Selected in Sub Folders

Selecting all descendants of a folder hierarchy in the world outliner doesnt accurately show what all is selected. This does not always occur and is a visual bug. The items in the level are still selected.

Found in 4.18 CL# 3832480, 4.19 CL# 4033788, 4.20 CL# 4302132, and 4.21 CL# 4348893

1. Open the Editor
2. Create two folders and sort various items from a level into them
3. Place the second folder inside the first folder
4. Collapse the folders and right click the top folder
5. Go to Select > All Decendants
6. Expand the second folder

Results:
The items in the second folder will not be highlighted in the world outliner however they are still selected in the level

Expected:
The world outliner would accurately show all items highlighted
