Result of getRetainingPath should not be about the getRetainingPath invocation.

Open leak_tracker at a14a2ec06a1b7e8f591fd9adbfd4295b903e4288 in VSCode.
Navigate to test/dart_debug/leak_tracking/end_to_ent_test.dart
Click 'debug' for the test 'Retaining path for not GCed object is reported.'

See in debug console the retaining path is about the vm call, not path in the test library, that user wants to discover:

It turned out to be result of two contexts living in the same function. After I moved leaking object from the test to a dedicated class, the issue disappeared.
Closing it for now, as we do not know what to do about it. If we will face the issue in other context, I will reopen the bug.
