Fix Studio Designer when creating view layout of a custom document type

When configuring the view layout of a custom document type, the view editor seems to go in the loop when inserting elements based on the configuration of the document type, the editor increases the height of the element. It stops after a few seconds, but there are reports of an endless increase until the browser crashes.

+How to reproduce::

• Create a new document type in Studio Modeler
• Assign the standard schemas File and Files
• Go to Studio Designer
• Go to Layouts > Local Document Types under the UI tab and configure the create layout of the new document type. The layout get generated based on schemas defined in the document type, so far so good
• Go to the view layout and configure it

Expected result: the layout should be generated without crashing the browser.
Actual result: . A window grows vertically indefinitely (and sometimes until browser crashes. See screenshot attached:
