Re: [PATCH 0/6] MR6609: jscript|mshtml: Add support for host object accessor props.

Please add some tests showing that props are indeed accessor properties. Their implicit use is covered by a number of other tests, but something simple like `getOwnPropertyDescriptor`, maybe paired with a getter/setter call using `call()` function, would be nice.
