How to stop the height re-sizing in full screen view

I am trying to find the javascript in this plugin to stop the page from changing in height in the full screen mode, when the page size is changed. On the tablets and phones, this does not happen, which allows all of the text and the featured image to fit before those ul dots. Is this somewhere within the .lSSlideOuter? I see this happening when I re-size the page, the “ul class testimonials-list lightSlider” the height changes. I would like to stop it from changing.

Again, I am hoping to find the javascript code for this. Or other code?

Any suggestions?

Thanks.
