I have MetaBox 4.13.4 installed and am using the Gutenberg plugin. I created a metabox that functions perfectly when I set the context to "normal" or "advanced". However, if I set the context to "after_editor", "after_title", or "form_top", the meta box does not appear on the page at all. The meta box does appear if I switch to the classic editor.
Code is here: https://pastebin.com/tue5Ezvz
Is there a plan to fix this so that these new contexts also work with Gutenberg?
