Avatar block alignment is not working well in some themes

[pitamdey]

Avatar block alignment is not working in some themes like Twenty Twenty-one, Twenty nineteen, Twenty Seventeen and Twenty Sixteen but it is working fine with Twenty Twenty-two & Twenty Twenty-Three.
The Main issue is that centre align is not reflected in editor side
Here is a Video of the issue along with how it works :

Thanks for the report!

This is an editor problem, so it should be fixed in the Gutenberg plugin first. Please report it on GitHub:

GB39794 added margin: 0 auto to an Avatar block element when centering it, but the .wp-block-avatar container does not get the .aligncenter class. It needs a different CSS selector (or it needs to add alignment classes).
