Subject

I use FOSCKEditor in a form and everything was working nicely.
But since I added a Vue (VueJS) in an upper element the editor isn't showing anymore.
The textarea isn't visible but isn't replaced by the CKEditor.

I have tested getting rid of everything in my Vue but the simple fact that it has been loaded seems to trigger the conflict.

Steps to reproduce

Create a new Vue in a .js with

var vm = new Vue({
    el: '#vm'
})

Then encapsulate the form (containing the CKEditor) with

<div id="vm">...</div>

And add to the same page
