Disabling embeds blocking is not working

Hi!

For my bad surprise i see that you handle embeds. For my case that is not needed and there was CSS conflict. 

I added 
`add_filter( 'air_cookie\embeds', '__return_false' );`
into my functions.php file but notthing happened and iframemanager.css file is still loaded.

I would like very much if this file would not be enqued if __return_false is defined in code.
