Same here, as I remember, it works fine in Preview-0.2

I'd think that Phil Nachreiner (@philnach) might have some thoughts in this area. I believe #1919 might improve this dramatically. I'd be curious to find out what caused this to regress since 0.2. Maybe something from Carlos Zamora (@carlos-zamora)'s accessibility work slightly regressed this as an unexpected side-effect?
