Zooming covers bottom of image

As seen in image 1 below (compared to image 2, unzoomed), the bottom bound for zooming is the device height rather than the toolbar at the bottom. This leads to issues on very large comics where it can become difficult or impossible to read the text at the bottom through the translucent toolbar.

The same goes for the right edge on landscape comic, so this is as far right as I can see on an iPhone 6 with a slight zoom in
