Bug Description

On our website, when I click a media image (let's say the Featured Image), I'm used to WordPress "selecting" that image for me in the media modal popup. When I enable the AMP plugin, I no longer see this behavior. When I disable the AMP plugin, I do see the the behavior.

Expected Behaviour

Please note that I am using the WordPress Gutenberg/Block editor here. I've not tested/replicated this in the "Classic" editor. Also, this is what happens when AMP is not running.

1. I go to edit an (already existing) post on my WordPress site. (It has a featured image set.)
2. I click the featured image on the post.
3. When I am transported into the media modal, I see the image which is selected as the featured image highlighted.

Steps to reproduce

Install and activate the AMP plugin. The above steps no longer work for me.

Screenshots

What's important to note about the above images is that my jars of peanut butter are the "Featured Image". But when I click that image, I do not see it selected in the media-modal.
