Regression: This selector is more specific than (well, equal specific but out of order from) and thus overrides the margin applied from .components-color-palette_clear:

Honestly, we shouldn't need margin here for the button. The color palette panel shouldn't be doing a negative margin. It should have a container and spread the options via display: flex & align-items: space-between
