Components disappear from 2D view after adding effect to root rectangle

Found issue:

Components disappear from 2D View after assigning and effect to root rectangle when there is some other component in 2D view that has an effect assigned.

Steps to reproduce:

• Create general empty project
• Drag and drop Rectangle component to 2D View
• In Effect Composer, create and save two different effects
• Drag and drop first effect to rectangle1 in Navigator
• Drag and drop second effect to rectangle (root rectangle) in Navigator
• -> rectangle1, button and label disappear from 2D View, also effect for root rectangle is not visible
• Select File -> Save all
• -> Components and effects visible again
