Bootstrap 4 problem

When switched to bootstrap 4.2.1 from bootstrap 3.3.7 there is a problem with bootstrap css.
I’m using code mirror in rtl -
direction: “rtl”,
rtlMoveVisually: false,
and when I enter numbers they are written from right to left without switching the direction - for example when I type 123 I get 321
Please help

Interesting. I didn’t think CSS could do that. I have no idea what would be causing it—maybe try deleting/bisecting Bootstrap CSS until it goes away to figure out what is going on.

When I removed bootstrap’s css it’s working ok
