Does swiper work in popup?

Question

css

Very incomprehensible behavior of the swiper slider in the modal window from bootstrap4.
I think it's easier to initialize the problem by going to the page itself https://mivimebel.ru/portfolio/

There is a blue carousel button , when clicked, the slider will come out, and it does not work. But if you open the browser debugger CTRL + SHIFT + I everything starts working. I don't understand how this is possible? Has anyone had a similar problem? I don't see any errors in the console.

Answer 1

the slider starts working after changing the screen size, dig in this direction
