Editor Limited Width Issue and Possible Fix

[FGP-Radio]

Description

So, for some reason, my Gutenberg editor will not go to full width (please see the attached screenshot). I believe this is a bug because it started out of nowhere and I can't get it to stop, and this is actually the second site that I have had this error on.

Possible fix:
After a bit of digging in Inspector, I found a couple lines of css which seem to be the issue. I have included two screenshots. One from before removing the below style tags and one after.
The issue lines are the "max-width: 620px;" in both of the following style tags.

They are listed below:

<style> .editor-styles-wrapper .edit-post-visual-editor__post-title-wrapper > :where(:not(.alignleft):not(.alignright):not(.alignfull)) { max-width: 620px; margin-left: auto !important; margin-right: auto !important; } .editor-styles-wrapper .edit-post-visual-editor__post-title-wrapper > .alignwide { max-width: 1280px; } .editor-styles-wrapper .edit-post-visual-editor__post-title-wrapper > .alignfull { max-width: none; } </style> <style> .editor-styles-wrapper .block-editor-block-list__layout.is-root-container > :where(:not(.alignleft):not(.alignright):not(.alignfull)) { max-width: 620px; margin-left: auto !important; margin-right: auto !important; } .editor-styles-wrapper .block-editor-block-list__layout.is-root-container > .alignwide { max-width: 1280px; } .editor-styles-wrapper .block-editor-block-list__layout.is-root-container > .alignfull { max-width: none; } </style>
