GATEKeeper on "[Plugin: Jetpack by WordPress.com] Query ignored on home page with Jetpack mobile theme"

We've enabled the mobile theme for one site, but when visiting the home page, a query at the top of the page is being ignored and won't display.

What could be causing this?

Here's the code:

<?php if ( is_front_page() ) {
	$upcoming = new WP_Query();
	$upcoming->query( array(
		'post_type'=> 'tribe_events',
		'posts_per_page' => 1
		)
	);

	if ($upcoming->have_posts()) :
		while ($upcoming->have_posts()) :
			$upcoming->the_post();
			?>

I tried taking out the if statement, so it appeared everywhere, but it still would not appear.
