When locking parent layer, sublayer is only displayed as locked if the sublayer contains specific elements (texts, spirals)

Steps to reproduce:

• open attached file from the below referenced link (this issue was created by request from Jonathan Hofinger in this related issue report --> #1893 (moved) Subject: Layers panel doesn't hide/show layer with PNG until actively using zoom

What happened?

When clicking on the lock icon next to the Eye/Visibility icon for the second parent layer from the top in the attached file, the lock icons in the sublayers do not lock/unlock after repeatedly clicking on the parent layer's lock icon. This seems to be a bug since clicking on the lock of the first parent layer in the hierarchy does change the lock icons to locked/unlocked for its sublayers. So the complete opposite behavior for the same type of layer in the same file.

What should have happened?

All parent layers should lock/unlock their sublayers when clicking on their lock icons.
