Maybe /u/Jagex_Stu can shine some more light on it.
I'm home for the weekend, so unable to review that bugfix from here.
As far as I know (we receive automated notifications whenever the status of a ticket we've deved is edited or commented, and I've not seen this one in my inbox the last few weeks), that issue hasn't been returned to dev, or copied to a release candidate, so presumably still awaiting or undergoing QA testing.
Probably not the illumination you hoped, but that's the light I can cast from the eldritch gloom of my man cave. :)
