Seems like the right time to add one!

Only in the "best time to plant a tree" sense. When someone was implementing DT-related font-y features would be the "right time".

No time like the present!

I have no doubt I will come to regret it as much as I always do when I add one-off bits for things like this, but I will see what I can do.

Awww. Another approach you could take, if you don't want to mess with WebCore::Internals is to add support in WebKitTestRunner (or just do it in TestWebKitAPI) that overrides [WKWebView _contentSizeCategory] and sends the UIContentSizeCategoryDidChangeNotification notification. It might make sense to override [WKWebView _contentSizeCategory] regardless so we have consistent testing on devices that might have had some changes (though I think your call in Internals::resetToConsistentState() should cover most cases).

That's what I assumed I was going to have to do when I was whining. The Internals thing is way less annoying (no bounce to the UI process, no asynchrony in the test, etc.).
