I think I just found a conflict with another plugin, WP Real Media Library.
TypeError: this.$input.data(...).map is not a function
and after that, a warning:
Source map error: request failed with status 404
Resource URL: http://localhost/wp/wp-content/plugins/real-media-library/public/lib/es7-shim/dist/es7-shim.min.js
Source Map URL: dist/es7-shim.map
When I disable WP Real Media Library, everything works as expected.
