Add iframe to picture-elements/picture-glance or add elements to iframe

[barrymossel]

Currently my camera stream is loaded in Lovelace through an iframe (as that works best in every way). I really want to show certain states of the sensors located at the camera area. I would really like to have the option to load the iframe within the picture-elements or picture-glance card. Other way around would be fine to: overlay elements/state-icons on the iframe (but that would feel as much more work).

Is this possible?

PS. reason for embedding the stream through an iframe are:
home-assistant/android#979
Stream through iframe doesn't consume bandwidth when not being viewed (either by switching tab (browser or lovelace view) or when "closing" the companion app).

home-assistant/core#23055
Stream through iframe doesn't give me any authorization errors.
