Bugs with latest posts block margins

I was noticing there were some issues with the margins in a latest posts block. I was able to correct it with the following css, but I think it's something you could check out.

.wp-block-latest-posts {
	margin: 0 0 0 0;
}
.wp-block-latest-posts__featured-image.aligncenter {
	margin-bottom: 0px;
}

@media (max-width: 599px) {	
	.wp-block-latest-posts.is-grid li {
		margin: 0 0em 1.25em 0;
	}
}
