CSS: font-size for Block-Table figcaption

Not sure if this is a feature request or a bug. Figcaption font-size is only defined for .wp-block-image, but missing for .wp-block-table, which is a bit inconsistent.

.wp-block-table figcaption {
	font-size: 13px;
	text-align: center;
}

should be added to main.css?

Cheers
