Mirrored pages with embedded videos

I’ve been testing your plugin on my multisite application.
We have a lot of pages with embedded videos. When there is a video on the page, rather than mirroring the source page, it takes you to the source page which is on another site. The whole purpose of the mirroring content is to keep people on the site.

Should this redirect be happening? Is there a solution for this?
