Quote block styling

Hi Eduard and others.

I’m having trouble with the styling of quote blocks. The quote source shows up smaller than the quote and I’ve been unable to find out where to edit the styling of the quote source. Screenshot: https://www.dropbox.com/s/stg28m1e8lp51ye/Bildschirmfoto%202022-07-27%20um%2011.26.50.png?dl=0

In Customizer → Typography I’ve set the font to “Default Family” and the text size to 16px. This setting does not seem to differentiate formatting of the quote and the quote source. Screenshot: https://www.dropbox.com/s/2dhfu7fxk2ghijd/Bildschirmfoto%202022-07-27%20um%2011.24.18.png?dl=0

In the block settings, there’s also a typography setting but it affects both, quote and quote source. Screenshot: https://www.dropbox.com/s/2d4al86l0bqlpvf/Bildschirmfoto%202022-07-27%20um%2011.24.34.png?dl=0
