AMP compatibility issues

[gravityrail]

From @westonruter:

FYI: When I run AMP on my blog with Jetpack it is catching these additional markup items as validation errors:
• Enqueued _inc/build/shortcodes/js/gist.min.js
• Inline script mentioning wpNotesIsJetpackClient
• Excessive CSS for modules/contact-form/css/grunion.css
• Enqueued modules/wpgroho.js
• Enqueued _inc/build/twitter-timeline.min.js

[stale]

This issue has been marked as stale. This happened because:

• It has been inactive in the past 6 months.
• It hasn’t been labeled `[Pri] Blocker`, `[Pri] High`.

No further action is needed. But it's worth checking if this ticket has clear reproduction steps and it is still reproducible. Feel free to close this issue if you think it's not valid anymore — if you do, please add a brief explanation.

This should be fixed by #10945

[westonruter]

@gravityrail The PR #10945 would only address a subset of the above, if anything. An audit of all of the modules' AMP compatibility needs to be done, and this issue I think could serve as an epic to that end.

[gravityrail]

My bad, you're right. I mis-read this in my eagerness to close stale issues.

Also needing improved compatibility is the Comments module. See AMP validation errors that are generated here: ampproject/amp-wp#1785 (comment)

Adding to this, we'll also need to make sure our different blocks, especially those that use forms and JavaScript, can be used with AMP.
