Enqueued block scripts and styles show as coming from AMP instead of actual plugin

[westonruter]

Bug Description

In legacy Reader mode, I noticed that when Jetpack is active and I add a block that enqueues a stylesheet, the stylesheet shows as the AMP plugin being the source as opposed to Jetpack:

When a Reader theme is selected, it shows Gutenberg as the source:

When Gutenberg is deactivated, it shows wp-includes as the source:

The same happens for scripts which are enqueued from a block.

When a script is enqueued due by a block, make sure it is attributed as the source. The Bad Block plugin is an example of this, specifically for a script which is registered and enqueued in the render_callback:

Interesting, if it is registered beforehand then its attribution is correctly identified.

Expected Behaviour

The plugin responsible for enqueueing a block should be shown as the source.

Steps to reproduce

1. Activate Jetpack.
2. Add the Eventbrite block.
3. Validate the AMP page.
4. Look at the Stylesheets metabox.

And:

1. Activate the Bad Block plugin
2. Add the block to a post
3. Save and validate
4. See that the script source is not shown to be bad-block.

Currently, the Issue is not able to reproduce with the current version of the Jetpack plugin along with previous versions of it (First scenario). However, the Issue is able to reproduce with the "Bad Block" plugin (second scenario), But in the stylesheet meta, It shows AMP and Bad Block as source plugins.

Another issue which may actually be the same as this one: #6231.

QA In Progress

⚠️ After activating the Bad Block plugin, adding a block to a post and revalidating the post, the Sources contains both Bad Block and AMP:

As far as I understand, the Sources should attribute those issues to Bad Block only. Is that correct?

Other notes:

• I got the same result no matter if Gutenberg was activated or not.
• The Jetpack Eventbrite Checkout block doesn't cause any AMP validation issues for me so I skipped this test.
