I'm sorry, who's page cache are you talking about? Page caches are (AFAIK) not really fleshed out in any spec, and the WebKit page cache *intends* to represent a 100% inert page. This includes the inability to receive events. Any exceptions in practice are a bug for us that we would strive to patch.

Can you provide a specific link to relevant threads you're thinking of? I can't guess what search terms you intend for me to use.
