How to Change Quick Documentation Font?

I've change the Font of Editor and Console to Source Code Pro. But I don't see any possible option to change the Font type in Quick Documentation window. It's very awkward to see a completely different font in Documentation window comparing it with my "Source Code Pro" Font setting.

I have seen multiple posts with same requests but it all recommends to file a request in yourtrack. Is it still not possible to change the documentation font?
