Carousel slider bouncing on the lefthand side when it slides

[optimido]

This is what I am getting using Edge (on the left hand side towards the end of the move) - https://www.screencast.com/t/vhNWdirw - is this a bug?

I can confirm this bug in the following browsers on MacOS:

• Google Chrome 55,
• Safari 10.

Is there anything happening with this or have I missed a solution somewhere else? Thanks
