User created widgets from widgets that are normally not focusable appear to break navigation when added to another widget even when focusable set to true

User created widgets from widgets that are normally not focusable appear to break navigation when added to another widget even when focusable set to true

Example: A widget with only a text block in it (text is NOT able to be set to "is focusable" true) that has been added to another widget via the user created section can be set "is focusable" true but does not cooperate with the default navigation.

Note: This appears to work in 4.13.2

1. Download the attached project
2. Open the project
3. Play in editor (takes a second for the widget to show up)
4. Try to use the arrow keys or a controller to navigate the widget (the text will turn red when focused)
5. Noticed that the focus never changes from the original focused widget

Expected: The focus would shift down/up when the down/up is pressed on the keyboard and/or controller
Result: The widget cannot be focused by default navigation even though they have been set to focusable
