Bug 134364 – DOM attributes on prototypes should be configurable

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Mark Hahnenberg]

Currently they're not due to the internal implementation of CustomGetters/CustomSetters vs. normal Getters/Setters. Allowing mixing of Custom and non-Custom Getters and Setters in the same slot will enable attributes on the prototype to be configurable.

Seems useful to also have a test that checks the result of Object.getOwnPropertyDescriptor. (something like, Object.getOwnPropertyDescriptor(event.__proto__, "eventPhase").configurable).
