Image lightbox/preview not opening

[GatorsUF]

I am having an issue with the expanded image preview not working. Meaning if I click on one of the images in the box on the right side of the txt2img/img2img tabs it won't open the image in a large lightbox/pop-up. Often times it just scrolls to the next image. This problem in very intermittent and sometimes the lightbox opens as expected.
