As I mention in many reviews, please consider avoiding a singleton in WebCore as it constrains our options in the future for process sharing. Rather, please consider the standard Page level delegation.

Ah, I see. I will look into that.

I’m not sure that an object is the best way to pass a function pointer. Could have used WTF::Function instead.

I would think we’d include Forward.h here.

final

final

That's a good point. My initial thinking was to create a system sound manager that could support new system sounds in the future, although there's a chance that may not happen.

Yes, I think this sounds good. I have filed https://bugs.webkit.org/show_bug.cgi?id=218616. Instead of using a singleton, I think this could be a member in the Page class.
