Thanks for splitting this out from #57841 👍
It is mostly testing well for me, in particular, in the editor.
When using a theme adopting wp-block-styles support and it comes to the frontend though I'm still seeing selectors that aren't wrapped in a :where() leading to a few visual inconsistencies.
From what I can tell it appears these styles might be from stylesheets included by core but take that with a grain of salt as I'm not well versed in how these block library stylesheets are handled.

Here's a few lines of code that might be handy for testing this PR - run it in the console and it inserts all the block examples into a post: var blockExamples = wp.data.select( 'core/blocks' ).getBlockTypes().filter( ( { example } ) => example ).map( ( { name, example: { attributes, innerBlocks } } ) => ( { name, attributes, innerBlocks } ) );
var createExamples = ( examples ) => examples.map( ( { name, attributes, innerBlocks } ) => wp.blocks.createBlock( name, attributes, createExamples( innerBlocks ?? [] ) ) );
wp.data.dispatch( 'core/block-editor' ).insertBlocks( createExamples( blockExamples ) ); |

After cherry-picking the fix from #60098 to this branch locally, everything is testing well for me.
- Primarily tested with 2024, 2023, 2021, and 2020.
- In each theme, checked with and without
add_theme_support('wp-block-styles') - Global styles were still correctly applied to each of the affected blocks
LGTM 🚢

@tellthemachines About the button outline bug that exists in 6.5. I think you mentioned that there will be further specificity changes that will fix the issue in 6.6. Do you know which PRs do this and in which case we can consider the "Backport to WP minor" label to include these in a patch WP release? |

@youknowriad #60106 will fix that issue because it reduces the specificity of the element styles that are currently overriding the Button styles in the non-iframed editor. It reduces specificity for global styles selectors across the board though; not sure if that change is small enough to be a good candidate for a minor release. Another option that would also fix the bug is #56649, which is a much smaller change. I found some issues in testing it though, so it might need some further work. |

What?
Starts breaking down #57841 into its component parts.
This PR only addresses block-library styles, reducing specificity of rules that might conflict with global styles added to those blocks.
Testing Instructions
This can be tested on classic and block themes, but particular attention should be given to those that add support for
wp-block-styles(that's what enqueues thetheme.cssfiles from each block).Check that the blocks with style changes in this PR still display as expected. Global styles should work as well in this branch as they do on trunk, because their specificity hasn't been changed in this PR.
