            Bug ID: 225453
           Summary: [JSC] Wrong names set for anonymous classes from
                    static class fields in some cases
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ticaiolima at gmail.com

The following example is setting the wrong name for anonymous classes:

```
class C { static InnerClass = class { static f = this.name; } }

print(C.InnerClass.name); // prints “”, but should print “InnerClass”
```

The following example does it correctly:

```
class C { static InnerClass = class { static f; } }

print(C.InnerClass.name); // prints “InnerClass”
```

Both Firefox and Chrome are returning “InnerClass” for both examples. This example came up from a spec bug pointed out on https://github.com/tc39/ecma262/pull/1668#issuecomment-608189621.
