This Heading is set to FULL WIDTH – it shows full width in editor. But the Media & Text block below is set to full width, but never shows full in editor.

Media & Text block
Just testing. I’m adding extra text to see how wide the text will go. But I can’t get this block to display as Full Width in the editor no matter what I do. Shows full width on the front end, but not the back. And the Full Width / Wide Width buttons don’t seem to always do what I expect them to, have to click a few times.
