Last slide style is cut off

[yahav10]

Hi, I'm having a slider with 2 slides that have the same size - both of the slides have box-shadow and for some reason, the last slide is cut off at the right side of the slide.
How can I change the slider width and set padding to the last: slide and make the box-shadow displayed?
For some reason in the sandbox I can't reproduce it, that's why I am adding a link to the sandbox.

By setting the padding inside the options object fixed my issue.

padding is not applied, for example, in a horizontal slider to the upper and lower boundaries
