Steps to reproduce the problem:
1. Open multiple tabs
2. Try to move the tab horizontally in order to rearrange its position

What is the expected behavior?
The tabs were movable amongst themselves i.e. you could change the position of a tab by horizontally dragging it to where you wanted

What went wrong?
The entire window is moving itself.

Did this work before? N/A
