Whole Webpage or Extra Blocks Loaded Inside AMP IFRAME

When navigating to the Magento AMP Product page, users may see a whole webpage or extra blocks loaded inside AMP Iframe

Here is an example of this issue on Magento 2 AMP page frontend:

Step 4

Remove the extra blocks you found in step 2 using layout instructions
