This. Updating 'custom_attributes' => [] delivers nothing.

This is working for me for example to allow a data-media-id attribute for images:

1. Add data attribute to allowed section:

'HTML.Allowed' => 'img[width|height|alt|src|class|data-media-id]'

2. Specify the data attribute in the custom_attributes section:

'custom_attributes' => [
    ['img', 'data-media-id', 'Text']
]
