Bug Description

The WordPress.TV embed block includes a custom script that causes a validation error in AMP. The script is not needed for regular operation of the embed block.

Expected Behaviour

The plugin should strip the custom script during sanitization.

Steps to reproduce

1. Add an embed block in the block editor with the following URL:

https://wordpress.tv/2019/10/08/the-history-of-wordpress-in-four-minutes/

2. Publish the post and visit it on its AMP URL.
3. See in the admin bar that the post failed validation for including a custom script.
