Altering Details block styles doubling .wp-block-details class in the output

By defaut Details block styles outputs styles for inner paragraph like:

.wp-block-details>:not(summary) {
    margin-block-end: 0;
    margin-block-start: var(--wp--style--block-gap);

If I want to change margin-block-start on the block level styles I use:

.wp-block-details>:not(summary) {
    margin-block-start: 0;}

BUT it outputs:

.wp-block-details.wp-block-details>:not(summary) {
    margin-block-start: 0;}

If I use the same in the Additional CSS section of Styles Editor it produce expected:

.wp-block-details>:not(summary) {
    margin-block-start: 0;}

In per block additional CSS via global styles, selectors for block names are automatically added. The following nested selectors will give you the expected results.

& >:not(summary) {
    margin-block-start: 0;
