Fixes https://github.com/WordPress/gutenberg/pull/21816/files#r471447642
Related: forum thread

This fixes a regression for the button block when the outline style is applied: unlike WordPress 5.4, the background color wasn't applied in this scenario.

Test

  1. Add a button.
  2. Select a background color.
  3. Set the style to outline (the background color should still be applied).
  4. Publish the post.

The expected result is that the button has the background color selected, both in the editor and in the front. Tested with the themes TwentyTwenty, TwentyNineteen, TwentySeventeen. This was the behavior in 5.4 that we regressed in 5.5.

When the .wp-block-button.is-style-outline .wp-block-button_link
selector was added, its specificity (030) overrode existing
theme selectors that had 020 specificity.

While testing this I ran into some odd behaviour,

  1. When I add a button, give it a solid background colour, and change it to outline, I see it correctly in my editor. However, when I publish and view my post then the background colour is missing.
  2. When I return to edit post and give the button a gradient background colour, it doesn't show correctly in the editor. However, when I update and view the post the gradient background works.

Follow up to #24599.

Using the child combinator (instead of the descendant combinator) narrows the selector without increasing its specificity. This should help reduce the likelihood of a style issue occurring when a parent element has an `is-style-outline` CSS class.

hi @sannevndrmeulen this fix hasn't yet made available. It will be in Gutenberg 8.9 (to be released this week) and WordPress 5.5.1 (to be released soon). So, unless you've compiled and tested specifically this PR, what you experienced is the current buggy behavior.
