            Bug ID: 202932
           Summary: Web Inspector:
                    inspector/model/remote-object-weak-collection.html is
                    failing
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2

The test is reliably failing on all platforms with the following diff:

Looks like a real issue as the entry is not being GC'ed after the key is deleted. It has something to do with the WeakMap capacity I believe as the test stops failing if one extra entry is inserted:

-        {expression: "weakMap.set({id:3}, 3); weakMap.set({id:4}, 4);"},
+        {expression: "weakMap.set({id:3}, 3); weakMap.set({id:4}, 4);  weakMap.set({id:5}, 5);"},
