Only standalone events are returned, not recurring events.

Somehow I am only able to create a sitewide ESS feed ( /?em_ess=1 ) with standalone events while the posts in it are in fact part of a recurring event.

<item type="standalone" unit="hour" priority="1">
	<name>Date: 2014-03-24T16:00:00 01:00</name>
	<start>2014-03-24T16:00:00+01:00</start>
	<duration>1</duration>
</item>

I noticed that in the plugin-code there is built-in support for recurrence, and recurrence works when a single parent recurring $event_id is given. It seems that the following only returns standalone (child) events when no $event_id is given:

File: /inc/views/ESS_Feed.php
EM_Events::get(
	apply_filters(
		'em_calendar_template_args', array(
			'limit'		=> get_option('ess_feed_limit'),
			'page'		=> $page,
			'owner'		=> FALSE,
			'orderby'	=> 'event_start_date'
		)
	)
)

Edit: /?em_ess=1&event_id=2 (the parent event) in fact returns

<item type="recurrent" unit="week" selected_day="monday" limit="3" priority="1">
	<name>Date: 2014-03-21T16:00:00 01:00</name>
	<start>2014-03-21T16:00:00+01:00</start>
</item>

… but /?em_ess=1 only returns the standalone child events…
