feature request: Tool in Observatory that helps to find the root object that holds back an instance from GC

[MikeMitterer]

The following SS shows a class that has two instances but should have only one. I cant figure out why the first instance gets not garbage collected. I fiddled around now for several hours, questions on Gitter but no chance...
It's nearly impossible that all those "from" entries are holding a reference to this particular object.

In addition to the issue I filed before, looks like two things are confusing:

• the confusing bit is word [ 3 ] of Context (2). Not a very intuitive description.
• the list format that makes it look like a set of inbound references rather than a reference of a reference of a reference.

regarding the latter, even I'm not entirely sure if I understand the misunderstanding right. maybe it would be better to use the inboundReferences UI than the list format.

regarding the former, maybe it would be better to show "variable [ 3 ] in Context of Closure". In fact, showing "var _context" is its own red herring...is there any way that it could show "var foo outside Closure" instead?
