New folder shortcut (Ctrl+Shift+N) does not work in multi-Content Browser layouts until a folder is manually focused

In multi–Content Browser layouts, the New Folder shortcut (by default Ctrl+Shift+N) does not work immediately after switching to another Content Browser tab. It appears that the editor does not automatically focus the folder tree on the left side of the Content Browser, which prevents the tab from recognizing the shortcut. Once the user clicks any folder in the left tree pane (or creates a folder through the right-click menu), the shortcut starts working normally in that pane.

Reproducible in UE 5.6 (launcher) and confirmed in CL 45937871 (source build from Main stream).

1. Open the provided repro project.
2. Import the layout "MultiContentLayout.ini" included in the attached zip file into the editor
3. Click on any Content Browser tab
4. Attempt to execute the new folder shortcut (Ctrl+Shift+N by default)

Result: shortcut does nothing in panes where no folder is currently selected in the folder tree. Once the user left-clicks a folder in the tree (or right-clicks to create a folder), the shortcut works in that pane.

Expected: the active content browser tab should expose its current folder path automatically so Ctrl+Shift+N works without requiring a manual folder focus.
