@rcbyr could you please consider merging this PR?

Thanks for your PR. But it doesn't work. Even if the last slide is displayed correctly, the first slide will then disappear. The problem has only been relocated. Since the slider does not duplicate slides, it probably does not make sense to activate the loop if there are too few slides. In this case there is enough space in the viewport to display all slides anyway.

What you said is true, but I want the loop because the slides in the slider are dynamic. so I want this functionality. Can you please see if you can add this scenario ?
