#22187 added support for SVGs in stories, but it looks like some elements were missed there.

For example, it is not possible to use <feBlend> in stories, whereas it works just fine in regular AMP pages.

I don't see why it shouldn't be allowed, so seems like an oversight.

Perhaps there are more tags that are missing as well.

Context: In the Web Stories WordPress plugin we'd like to create stories containing an SVG which uses <feBlend>.

Reproduction Steps

  1. Open AMP playground
  2. Select "AMP for Stories"
  3. Insert the SVG below within <amp-story-grid-layer>
  4. See validation error

Relevant Logs

The tag 'feblend' may not appear as a descendant of tag 'amp-story-grid-layer'
