Comment (by jonsurrell):

 I searched for selectors in Gutenberg block library
 [https://github.com/WordPress/gutenberg/commit/b1d943f027532a9e83b2739930d218c67f7f930d
 at commit b1d943f] and came up with this list of the selectors used:

 {{{
 .blocks-gallery-caption
 .blocks-gallery-item
 .blocks-gallery-item__caption
 .wp-block-form-input__input
 .wp-block-form-input__label-content
 a
 a:not([download])
 a[download]
 audio
 blockquote
 cite
 div.wp-block-gallery figure.blocks-gallery-image img
 figcaption
 figure > a
 figure a
 figure img
 figure video,figure img
 figure
 footer
 h1,h2,h3,h4,h5,h6
 h2
 hr
 img
 input
 ol,ul
 p
 pre
 table
 tbody tr
 td,th
 tfoot tr
 thead tr
 ul.wp-block-gallery .blocks-gallery-item
 }}}

 [https://github.com/WordPress/wordpress-develop/pull/7857 The
 implementation proposed in PR7857] \\does not support\\ the following
 selectors from that list:


 - `a:not([download])` (pseudo-class `:not()` unsupported)
 - `div.wp-block-gallery figure.blocks-gallery-image img` (use of class
 selectors in non-final position)
 - `ul.wp-block-gallery .blocks-gallery-item` (use of class selectors in
 non-final position)
