 This ticket tracks the backporting of PHP files for the following
 Gutenberg changes:

 https://github.com/WordPress/gutenberg/pull/59114

 The previous selector used for link styles set on an individual block
 instance simply used the `a` element. This meant it incorrectly was
 applied to buttons as well.

 The linked Gutenberg PR fixes this by updating the selector to match the
 one used in theme.json i.e. `a:where(:not(.wp-element-button))`.
