Blank Gallery-Edit or -Add-Panel with WP 5.3 and EML

Dear EML-support,

i ran into that issue:

• I use a enfold child theme, EML, WP 5.3, Yoast-Plugin, WPML for Media
• Issue: opening a existing gallery brings up the gallery setting (“edit gallery”); the very same issue occurs when creating a news gallery; a new gallery opens with panel “add images”
• then, whenever i want to switch panels (in existing gallery to “add images” or in a new gallery to “edit gallery”), the panel switched to is completely empty / blank. White panel only
• then i discovered the code below on the js console of Chrome. I dug into the code and could find out, that within function “this.cleanup” is one time called with this.listener being null. I strongly assume that’s the problem.
• this function is part of “backbone.min.js” which is part of the regular wp-includes

To get an idea who is causing the error, i did:

• Deactivate WPML-Media – nothing changed
• Deactivate YOAST-SEO-Plugin – nothing changed
• Deactivate EML – error disappered!!!
• applied this fix, but didn’t help

So, the only thing helping is to deactivate EML.
But i really want to use it.

Can you please fix this?

Thank you, Sam
