Sometimes text can have single lines of text (widows and orphans) from a paragraph that dangle at either the beginning or end of a block of text, which blocks readability. Unless this Gutenberg issue gets implemented, one solution could be adding the code below (or something similar that achieves the same) in style.css to prevent that from happening.

/* Progresive enhancement to reduce widows and orphans.
/* <https://github.com/WordPress/gutenberg/issues/55190>
*/
h1, h2, h3, h4, h5, h6, blockquote, caption, figcaption {
		text-wrap: balance; /* Safari fallback */
		text-wrap: pretty;
}
p {
    text-wrap: pretty;
}
