[BS4] Carousel not working well in IE11.
Created by: pappabj0rn
I'm seeing several issues with the carousel in IE11.
- Transitions don't really work
- Indicators are a bit of to the right
- During transition, captions from both current and next slide are showing
Tested on Win 7, 8.1 and 10 with IE11.
