The address for plugin.js: https://domain.com/owncloud/assets/plugins/preview/plugin.js
and theme.js : https://domain.com/owncloud/assets/themes/modern/theme.js

while without assets it loads https://domain.com/owncloud/apps/ownnote/js/tinymce/plugins/lists/plugin.min.js

I have no idea how assets works but it was recommended for gallery + (https://github.com/interfasys/galleryplus/blob/stable8/README.md) and I follow this https://doc.owncloud.org/server/8.0/admin_manual/configuration_server/js_css_asset_management_configuration.html
