The Meta Fields tab does not work

I’m encountering a persistent JavaScript error when using WPBulky – WordPress Bulk Edit Post Types together with LearnDash custom post types (for example, sfwd-quiz, sfwd-course, etc.).

Whenever I open the WPBulky editor page for these post types, the browser console shows:

Uncaught ReferenceError: QTags is not defined at admin.php?page=vi_wpb_bulk_edit_sfwd-quiz:3989

Because of this error:
⸻ • The page stops loading correctly.
⸻ • The Meta Fields tab does not work.
⸻ • The Save button shows a spinning loader forever and never completes the AJAX request.

I’ve confirmed that this happens before any manual interaction — the error is thrown as soon as the page loads.

Technical findings
⸻ • The variable QTags is normally provided by quicktags.js in the WordPress Classic Editor.
⸻ • However, LearnDash post types (and other custom post types) do not enqueue quicktags.js, so QTags is undefined in those admin pages.
⸻ • WPBulky’s inline JavaScript assumes that QTags already exists and calls it immediately, which causes the page to crash.
Here is the exact context of the error: Uncaught ReferenceError: QTags is not defined at admin.php?page=vi_wpb_bulk_edit_sfwd-quiz:3989

✅ What I’ve tried
⸻ • Verified that AJAX endpoints (vi_wpb_get_meta_fields and vi_wpb_save_meta_fields) work fine in other post types.
⸻ • Manually defined window.QTags in the console — when I do this before the page runs, the error disappears and the plugin works perfectly.
⸻ • Attempted to enqueue quicktags.js and inject QTags through PHP hooks like admin_print_scripts, admin_head, and in_admin_footer, but none of these fire early enough because the inline JS executes before they run.

⸻ • WordPress: 6.8.3
⸻ • WPBulky: Premium 1.1.9
⸻ • LearnDash: 4.25.6
⸻ • Theme: Divi
⸻ • PHP: 8.3.27 (Supports 64bit values)
⸻ • Server: Linux 6.8.0-86-generic x86_64 (Apache)

Thank you so much for your help and great work on this plugin.

Best regards
