Using required argument in the checkbox field with typography as parent

[bilal-pp]

Hi, I want to display some checkbox fields only if the parent typography filed's font-family equals to any of the google fonts. Below is the sample code:

                           array(
				'id' => 'heading_font',
				'type' => 'typography',
				'title' => 'Headings',
				'output' => array('h1','h2','h3','h4','h5','h6'),
				'font-weight' => false,
				'font-style' => false,
				'text-align' => false,
				'line-height' => false,
				'color' => false,
				'font-size' => false,
				'google' => true,
				'subsets' => true,
				'preview' => array(
					'text' => 'Heading Preview',
					'font-size' => '30px',
					'always_display' => true
				),
				'default' => array(
					'font-family' => 'Open Sans',
					'color' => '#000000',
					'font-size' => '30px',
					'google' => true,
				)
			),
			array(
				'id' => 'checkbox_1',
				'desc' => 'checkbox_1',
				'type' => 'checkbox',
				'required' => array('paperplane_heading_font_options', 'equals', 'Overlock')
			),
			array(
				'desc' => 'checkbox 2',
				'id' => 'checkbox_2',
				'type' => 'checkbox',
                                    'required' => array('heading_font', 'equals', 'Overlock')
			), 

But the above code does not work, the checkbox fields are hidden but even after changing the font-family to Overlock, checkbox fields won't appear. Could you guys please provide me the solution.

Trying pulling v.3.6.4.2 from this repo. The issue should now be solved.
