Steps to reproduce: 1. Create a Volume and put some assets in it. 2. Create a CKEditor field and put it on the Volumne's field layout. 3. Go to Asset index page and double click an asset to edit it. 4. Add some data in the CKEditor field and save. 5. Edit the Asset again and notice the data didn't save. No JavaScript errors, looks like it's just missing in POST data on save. **Versions:** * Craft 3.0.10.1 * CKEditor 1.0.0-beta2
