Thank you, @aovcina, for your PR! I've reviewed it and found some edge cases where unusual behavior occurs during aggressive dragging. Instead of abruptly cutting off the drag action, I suggest preventing the track sliding from exceeding its thresholds by dynamically adjusting the trackTransform computed variable.

@ismail9k, thank you for the feedback. I've reviewed and tested made changes and you're right. It's better to handle it within the trackTransform computed. Along the way, I've added prop validation so developers are informed that the newly added preventExcessiveDragging option cannot work with wrapAround. Also, I've added a badge in the docs for the new config property with the upcoming minor version that indicates its availability. Please amend if needed.
