Prefab Edit Mode shows scene instead of just the prefab

Unity 2019.1.b8 AND Unity 2019.1.b9

In Unity I have a prefab that looks like this:


In my scene I have several instances of this prefab:


When I select one of these prefabs and open prefab edit mode, it still shows all the prefab instances and it turns of the lighting. I expect that it would only show a single prefab instance when editing:


Is this a known issue, or should I submit a report?

Best,

So, guess the lighting was just the light toggle.
I created a brand new scene, and confirmed the same behavior persists.

Additionally, its worth noting that in the scene when selecting an object in the prefab the transform handles and collider gizmos show up in the scene view, as expected:


However, in prefab edit mode, the tranform handles and collider are invisible:

 

Unfortunately I'm unable to reproduce the bug today :/

 

The behavior happened again. Haven't yet determined a pattern for when it does and doesn't happen.
