editor.css application in Sage 10

Testing

app.build.items.precss.setLoader('minicss');
  app.hooks.action('build.before', (bud) => {
    bud.extensions.get('@roots/bud-extensions/mini-css-extract-plugin').enable(true);
  });

as mentioned by @oxyc at Compile CSS files in dev mode - #9 by oxyc .

Seems to be working. I see font styling applied on desktop, tablet and mobile in Gutenberg editor now. Do not seer two columns for tablet yet though, but perhaps

,,,
* Desktop: Three columns */
 .wp-block-cover .block-editor-block-list__block.wp-block-columns {
    display: flex;
    flex: 1 1 calc(33.333% - 20px);
}

/* Tablets: Two columns */
@media (min-width: 763px) and (max-width: 1024px) {
     .wp-block-cover .block-editor-block-list__block.wp-block-columns {
        flex: 1 1 calc(50% - 20px);
    }
}

/* Mobile: One column */
@media (max-width: 762px) {
     .wp-block-cover .block-editor-block-list__block.wp-block-columns {
        flex: 1 1 100%;
    }
}
,,,

in editor.css don’t get applied properly. Checking some more.

Post yarn dev in Sage 10 in editor on tablet view I also get
