[Gutenberg] Fixing any issues with rendering native blocks in AMP

[postphotos]

As a WordPress site running Gutenberg, my core/native blocks should be renderable as AMP-HTML compatible markup.

AC1: Any issues previously identified with core blocks from #845 should be fixed here.

More Blocks Supported

Hi @miina,
Please see this comment on #845, if you haven't already. I marked more blocks as supported.

@westonruter Looks like as of now the only non-supported core blocks is the Categories with dropdown block. The issue there seems to be removing the script that's handling the option selection. For this specific case maybe a separate AMP_Block_Sanitizer for processing the comments wouldn't be necessary and we could just replace the render_callback of the block (similar as your Categories Widget solution) for the AMP page. Thoughts?

Hi @miina and @kienstra:
I've updated the issue here with a formal Story and Acceptance Criteria. When #845 concludes, let me know and I'll flesh out what's here based on your discovery. Thanks!

Oh also @miina pointed out that AC1 from #1008 may apply here. 👍

Results Of Discovery

Hi @postphotos,
Thanks for adding the Story and AC to this. The discovery from #845 is complete, though the results are on this wiki page. The only block with issues is Categories with a dropdown.
