wordpress use margin-left:auto; margin-right:auto to achieve centering effect,
so <img> need add display:block or add display:table for <figure>; old version bricks have this css, but bricks2.0 have not. (need fix it)
Another way to achieve this is to add an exact width to <figure> instead of auto.
(this have bug on old bricks version too)
for example, add image on row block, and set center,
on front page, you will find it don’t work.
need add exact width to <figure>, it will work fine, but on gutenberg editor, there is no convenient way to add
