[Bug]: Class layout label position & inheritance issue

[NiklasBr]

Expected behavior

Having a fieldset or other layout component inside another should work with regards to label positioning. Parent should not override child.

Actual behavior

Only the positioning closest to the root of the layout definition works.

The "Test Text" label should be positioned to the left, not top:

Steps to reproduce

1. Create a localizedfield, or any other layout container.
2. Set label position to e.g. top.
   
3. Add a new layout container of some sort into the one created earlier, set the label position to something else, e.g. left.
