CSS inside <head> tag not applied to HTML embed code from CMS

I have HTML embeds inside of a rich text field of a post inside of my CMS. Within these embeds I am creating a div and attaching an id to them.

I tried to place CSS inside of the Custom Code head tag of the page settings and they do not seem to be applied to the div inside of the HTML embed even after publishing.

My workaround right now is to place the styles inline in the embed. Is there any way to make this work using the head tag?
