Selection Objects Are Not Removed After Adornee Deletion

[Bobytoeburrito (Innovator)]

Description

I am unsure if this is intended behavior, a bug, or a multifaceted issue.
If certain objects* have their adornee set to a part and that part is deleted, the selection is not unrendered and instead remains visible. Upon further investigation, I noticed other objects** that use adornees do not demonstrate this behavior; however, the adornee is still set to the now-deleted part. This is also true of seemingly all properties that accept an object value in that deleting the object does not reset the object value to nil.

Not a bug.

Or rather, we would have considered this a bug at some point but it’s been this way for long enough that it has turned into the expected behavior.

There’s many cases out there of adorning SelectionBoxes and HandleAdornments to parts which aren’t in the workspace, so there’s probably no feasible change we could make to the behavior without breaking too many things.
