# Event Handling
# --------------
# Add default event behavior (click link to navigate, click button to submit
# form, etc). We start by wrapping dispatchEvent so we can forward events to
# the element's _eventDefault function (only events that did not incur
# preventDefault).
dispatchEvent = core.HTMLElement.prototype.dispatchEvent

# -------
# Need to use the same context for all the scripts we load in the same document,
# otherwise simple things won't work (e.g $.xhr)

# ---------------

# Fix resource loading to keep track of in-progress requests. Need this to wait
# for all resources (mainly JavaScript) to complete loading before terminating
# browser.wait.
