[react-slick] Reverse swipe from last slide ignores slidesToScroll and active dots disappear (infinite=false)

When the user reaches the very last slide and keeps trying to swipe forward (knowing nothing is there), then tries to swipe backward again, two issues occur:

1. On the first reverse swipe, the slider only scrolls 1 slide — even though slidesToScroll is set to 2.

   • From the second reverse swipe onwards, the slider scrolls correctly by 2 slides.

2. After swiping beyond the last slide, the active dot indicator disappears.

   • When swiping back, the active dot does not match until the second swipe.

My settings

const settings = {
  dots: true,
  infinite: false,      // important: finite mode
  slidesToShow: 2,      // or 3/4 depending on screen size
  slidesToScroll: 2,    // should always scroll in pairs
  speed: 500,
  arrows: false,
  adaptiveHeight: true,
};

Expected behavior

• Every swipe (forward or backward) should respect slidesToScroll.
• The active dot should always remain visible and correctly reflect the current position.

Actual behavior

• Forward overswipe at the end does nothing (✅ correct).
• First reverse swipe → scrolls only 1 slide (❌ unexpected).
• Subsequent reverse swipes → scrolls 2 slides (✅ correct).
• After overswiping forward at the end → the active dot disappears (❌ unexpected).

Question

• Is this a known bug in React-Slick / Slick?

• Is there a recommended workaround or fix so that:

  1. Reverse swipes from the last slide always respect slidesToScroll.
  2. Active dots never disappear after overswiping beyond the last slide.
