Antialiasing Not Working in Safari?

When I build for Web Player and run in Safari (9.0, Mac OS 10.10.5), antialiasing is turned off, no matter how I have it set in Quality. I can clearly see antialiasing set to 4x working in the editor, but not in the browser. In this particular case, it’s pretty noticeable as there is a thin object that disappears at certain angles with antialiasing turned off.

I’ve found several old threads on this, and I thought the issue had been resolved, but apparently not. Is it not possible to use antialiasing in Safari?

I just ran across this link:

As I said, I thought it had been fixed, but it’s happening now.
