there is an issue with your jQuery plugin when trying to display PDF documents that have page width greater than height. If height is greater or equal to width, then the display is correct. Otherwise the book's page colours get messed up, as in the example: https://pasteboard.co/JIeWkpI.png (page colour should be white).
Also, after resizing window, the issue disappears and the book is displayed correctly. But only until new pages are loaded, then the issue reappears.
Could you provide a solution to this?
