PHP Warning when menu editor is used in preview

Hello,

I used menu editor in preview mode, with a editor role, in my case:

/wp-admin/customize.php?autofocus%5Bpanel%5D=nav_menus&return=%2Fwp-admin%2Fnav-menus.php%3Faction%3Dedit%26menu%3D[ID OF A MENU]

I’ve got two warning:

<b>Warning</b>: Undefined array key “editor” in <b>wp-content/plugins/advanced-gutenberg/init.php</b> on line <b>116</b>

<b>Warning</b>: Trying to access array offset on value of type null in <b>wp-content/plugins/advanced-gutenberg/init.php</b> on line <b>116</b>

This is because you assume that the settings for the editor role are done but this is not necessarily the case. It will be necessary to test if the settings are in place.
