Resolve issues stemming from WP's global margin-block-start and margin-block-end rules

Is your suggestion related to a problem? Please describe.

There are two global CSS styles coming from WordPress relating to spacing supports:

.wp-site-blocks > * + * {
  margin-block-start: var(--wp--preset--spacing--10);
}

and

.wp-site-blocks > * {
  margin-block-start: 0;
  margin-block-end: 0;
}

Within body content these are fine, but outside of that they interfere with layout elements. Find a way to disable them, or override them.

Describe alternatives you have considered.

This stemmed from an issue in Core where layout styles were overriding global margin styles (see #43404). As of WP 6.3 this has been fixed in Core by reducing the specificity of the layout styles.
