How to avoid CKeditor to load files when it's invoked - yii2

Question

I use CKEditor in a modal window, so it's "invoked" when the modal is shown.
When this happens I see CKEditor try to loads files like:
ckeditor/lang/es.js?t=J5S8
ckeditor/styles.js?t=J5S8
ckeditor/plugins/confighelper/plugin.js?t=J5S8
ckeditor/skins/moono-lisa/editor.css
...
I tried to load all these files in the page, but when CKeditor is invoked it tries to load again more files, even the ones I already loaded.
This is a problem in my case because I use an AssetManager and Minification system in my framework (Yii2), and since everything is packed in one file, CKeditor fails when it tries to load again files.
Is there any way to preload everything that CKeditor will need, in order to have the Assets and Minify process working well ?
My CKEditor config is:
CKEDITOR.replace('#editor', {
customConfig: '',
height: 200,
language: 'es',
extraPlugins: 'confighelper',
removePlugins: 'elementspath',
resize_enabled: false,
toolbarLocation: 'top',
toolbar: [
{ name: 'styles', items: [ 'Format' ] },
{ name: 'basicstyles', groups: [ 'basicstyles', 'cleanup' ], items: [ 'Bold', 'Italic', 'Underline' ] },
{ name: 'links', items: [ 'Link', 'Unlink' ] },
{ name: 'clipboard', groups: [ 'clipboard', 'undo' ], items: [ 'Undo', 'Redo' ] },
{ name: 'editing', groups: [ 'spellchecker' ], items: [ 'Scayt' ] },
{ name: 'tools', items: [ 'Maximize' ] },
]
});
