# This class handles rails' remote form 'ajax:aborted:file' event to serialize
# forms with files and send them through ajax using the `FormData` HTML5
# feature.
#
# The general approach and request implementation respects the same lifecycle
# of original rails' remote form requests, to allow existing handling code
# to run without any modification.
