ESC key stopped working in file preview dialog of solution submission

[kliberf]

At solution submission page, teachers can preview the content of a submitted file. A while ago, it was possible to close the preview dialog by pressing escape key on the keyboard. This is no longer possible, and one has to scroll back up and use the X button on the top right of the modal window. Would is be possible to reintroduce this functionality?

Thanks for the feedback, I already have this one in my todo list and I plan to address it soon. This was probably caused by AdminLTE upgrade.
