Lightbox size is not dyanmicaly responsive to mobile device orientation

First let me say this is a great plugin!

I find that although the grid gallery and the lightbox are responsive, the lightbox size isn’t when you rotate from portrait to landscape (or vise-versa) on a mobile phone.

Not a huge problem but an asthetic one.
