Issue 9769 is still open.  It looks like there was some disagreement in the comments between Alexander and Victor as to whether a new issue should be created (since Victor had a different idea when first opening the issue), but it looks like Victor deferred to Alexander in his final comment.

I will close this issue as a duplicate, and if you could repost your patch on the other issue, that would be great.  The discussion there is relevant to your patch.
