[2.0.5] Undefined array key "source" in ui_patterns_ui

Problem/Motivation

I'm seeing some warnings pop up in my logs though and wondered if it's something I'm configuring incorrectly or if you all are aware of them already.

Here's the dump:

Steps to reproduce

Added a form to any component by navigating to /admin/structure/component and choosing any component. Then added the component via Layout Builder to a page within a section.

Proposed resolution

I don't have much but, in ui_patterns_ui.module on line 90 it looks like it's trying to get a source key that doesn't exist on some of my things.
