custom media frame and issues with Edit Image link

I’m creating a custom media frame with the following code for my plugin:

zFrame = wp.media.frames.customImage = wp.media({
	title: 'Choose Image',
	library: { type: 'image' },
	id: 'z-frame'
});

The “Edit Image” link that appears in the right column opens in a new window when clicked. Meanwhile, native versions of the media frame, such as for Featured Image, have the “Edit Image” link update the view in the current window. How do I prevent the link from opening a new tab? Is there an option I’m missing for wp.media?
