 Post WordPress 5.4, the Gutenberg plugin now syncs up the button markup in
 the editor with what's rendered on the front end:

 https://github.com/WordPress/gutenberg/pull/21266#issuecomment-611344160

 Old button markup:
 {{{
 <!-- wp:button -->
 <div class="wp-block-button"><a class="wp-block-button__link">My
 button</a></div>
 <!-- /wp:button -->
 }}}

 New button markup:
 {{{
 <!-- wp:button -->
 <a class="wp-block-button wp-block-button__link">My button</a>
 <!-- /wp:button -->
 }}}


 ----

 Twenty Nineteen's editor styles for the button block currently target the
 `.wp-block-button__link` selector as a child of the `wp-block-button`
 separator, but that's no longer the case. As a result, these button editor
 styles aren't getting picked up when using the Gutenberg plugin.

 This should be corrected. In order to provide compatibility with earlier
 Gutenberg versions, changes here should probably end up preserving the old
 selectors too.
