Version

4.0.1

Description

Sometimes the carousel is attached to the mouse while dragging. It's not easy to reproduce. Most of the times, it happens when dragging released above splide__arrow.

We had some bigger splide__arrow. Then it's happen faster.

Sample movie, happens at 7sec.

Works fine in chrome. Unfortunately firefox still has the bug.
