The implementation of _cacheModelChangedNotification will take a higher cache model even if the WebPreferences object that is changing is not bound to a WebView. Weird, but that is legacy behavior. You could update this comment.

Sorry but I'm rolling out this patch since I don't know how to fix this build failure.

My guess is to fix this issue you probably just need to reorder (or forward declare) the method. WebPreferences.mm:226 calls the method which is defined later in the file. Newer compilers just get this right, but in older compilers the order matters.

Thank you for reverting. I went to bed before the bots went red.

Yep, that is why that worked locally.
I'll fix that...
