embed pages shouldn't get minified css/js files when minify is set to manual

[superpoincare]

This is a bit like the amp bug where minified css and js files would be inserted in the pages.

Wordpress has the embed feature where some site can embed a post from your site.

The page created has an embed/ at the end of the URL.

Caching the page is fine but minified css/js files shouldn't be served if minify is manual.

This can be prevented by adding embed/ in the "Never minify the following pages" but it's not the best solution like the amp bug.

I think this bug will be present in both the original and the fix.
