Symptoms

When you try to set a parent layout for the layout you are currently editing, the GUI is broken and shows a string like use data-tooltip-content="content text" attribute to create a content.

Because of this, you are not able to connect the layout to a certain other (parent) layout.

Workaround

As a workaround:

Insert a Child Layout cell into the layout you are editing.
Set the correct parent layout.
Remove the Child Layout cell again, then save.

The parent layout will be assigned and work correctly. Also, the related GUI will not be broken anymore.
