Bug Description

I am using AMP in Standard Mode and it completely messes up the customizer preview of my website. Several things are not like I have set them up in the customizer and are different than my website looks on the frontend:

• Link colors are in a color that I was using on my website previously

• Background color is the Twenty Twenty default

• Text font is still Times New Roman and not changed

Checking the CSS of my website shows the old link color and the Times New Roman font that I see in the customizer stroked through and the Twenty Twenty background color grayed out.

Expected Behaviour

I would expect the customizer preview show my website as I see it on the frontend.
I would also expect that the changes I make in the customizer are replacing the original CSS and not overwrite them. But I am not sure if it is supposed to be that way.

Steps to reproduce

Assuming you are running AMP in standard mode:

1. Go to Appearance > Customizer and change the style of the Twenty Twenty theme
2. Look at preview and see that the changes you made are not previewed
3. Click Publish and see that the changes are shown on your frontend
