Issue description

Cannot inspect a node on a remote tab if a node's script contains typed dictionary (non typed dictionary is fine), and the dictionary contains an entry that has a Node object as a key.

• Custom class object inheriting Node as a key -> Error.
• Custom class object inheriting Node as a key, but dictionary is not typed -> Fine.
• Custom class object inheriting Node as a value -> Fine.
• Custom class object inheriting Resource as a key -> Fine.

Steps to reproduce

See Above, check MRP.

• Core: Add typed dictionary support for binary serialization #98120 should fix this. Please test it.

EDIT: I tested it, the bug is not fixed.
