Styling of select2 vs. regular select

[mbaas2]

I'm struggling to get proper layout for the select2-Controls in Bootstrap4.
Here's a fiddle with comments about the issues.
I'm not sure if this is a real "bug" of if I am not using it correctly - would appreciate some help!

I guess you've probably figured it by now, but you must add containerCssClass: ':all:' and use select2 full for the theme to work properly.
