edit_form_after_title is a classic editor PHP hook that fires within the post editing form rendered by edit-form-advanced.php. The Block Editor (Gutenberg) replaces that PHP-rendered form with a React-based JavaScript UI, so classic editor hooks like this one are not expected to fire.

This appears to be intended behavior rather than a bug. For extending the Block Editor, the recommended approach is to use the Block Editor's own extensibility APIs such as [SlotFills](​https://developer.wordpress.org/block-editor/reference-guides/slotfills/) (e.g., PluginPostStatusInfo, PluginDocumentSettingPanel).

Changing type from defect to enhancement. Needs dev feedback on whether providing a Block Editor equivalent for this hook is something worth pursuing.
