gutemberg blocks “change aligment” doesn’t work

Firstable thanks for the amazing theme and support.

I found an issue: gutenberg blocks (like an image in a post) set to full width don’t show full width.
I installed the demo page, and in customize/layout/site container/ is set to 800px width, and the default container is Normal. I want the blocks (like paragraphs) maintain 800px, but the images set to full width go up to it.
I only can get full width by changing “Normal” to “Full Width/streched”, but it also ignores the 800px.

I found a solution here: https://weblines.com.au/gutenberg-blocks-wide-alignment-full-width/#devaside , maintain the default container to Normal and 800px and:

– adding the snippet to functions.php:

<?php
/**
 * Register support for Gutenberg wide images in your theme
 */
function mytheme_setup() {
  add_theme_support( 'align-wide' );
}
add_action( 'after_setup_theme', 'mytheme_setup' );

– and also this, to the css:

.entry-content .alignwide {
        margin-left  : -80px;
        margin-right : -80px;
    }
    .entry-content .alignfull {
        margin-left  : calc( -100vw / 2 + 100% / 2 );
        margin-right : calc( -100vw / 2 + 100% / 2 );
        max-width    : 100vw;
    }
    .alignfull img {
        width: 100vw;
    }

This is my clean installation using only the woostify wizard: https://mimay.es/oneact/2018/10/16/when-feeling-tired-of-human-relationships/
