Cache not cleared when new params are added

[thijskaspers]

Hi there,

We noticed that the cache won't be cleared after we add some additional params. I was embedding a Wistia video which generated an iframe URL. Then I set the wistia_type param to 'seo', which should then generate a different embed_code, but it didn't.

Shouldn't the full oEmbed URL be cached, instead of the url of the video?
