Eyedropper of the Parent property can create bogus self-reference
Closed, ResolvedPublicBUG

Description

Relayed from BA.

Blender Version
Broken: 2.79b to 2.92 master
Worked: 2.78c

Short description of error

Using the eyedropper of the Parent property, if used on the same object, leads to creation of a custom property 'parent' on that object, with a reference to it. This can result in data that is never orphaned.

Exact steps for others to reproduce the error

In the default scene, select the cube, open Relations tab in properties, click the eyedropper on the Parent field and click on the cube. And error message will indicate 'Failed to set value'. However, user count for the object will increase to 2, and a custom property 'parent' will be created for the cube.

@Philipp Oeser (lichtwerk) sorry, that was unintentional. Looks like me editing the description removed you as assignee.
