Description Chris Dumez 2018-02-05 20:09:38 PST 
Make [OverrideBuiltins] a no-op outside the normal world. This is a legacy feature that is only needed for backward compatibility.
Let's try and make it a no-op outside the normal world.

This seems weird to me. This would mean that the same code written for a normal page would run different in an isolated world. If we want to make coding in an isolated world easier, I would rather it be an opt-in mode for the specific isolated world.

Ok, made it opt-in at Cocoa/C API level.

This has implications in the structure of prototype objects.

Please add a test case in the main world as well.
