Note: This is a blocker for the extended block style variations feature and section styling.

Problem

To support applying block style variations in a nested fashion, the specificity of block style variation selectors needs to be 0-0-0.

The Social Links block uses the button component in its edit UI. This means those buttons are given padding styles with a higher specificity than what we need to lower the block style variation selectors to breaking some of the default styles for that block's variations.

Further context can be found in #61032 and this comment.

Potential Solutions

There are two options to work around this;

1. Refactor the Social Links block to use simple button elements rather than the Button UI component within the canvas.
2. Add an "unstyled" variant to the Button component to avoid the higher specificity padding styles.

It's probably best to avoid using UI components within the editor markup for a block and option 1 is also likely the smallest change overall.
