Bootstrap 4 Modal backdrop getting darker with Turbolinks

I’m using Livewire and Turbolinks with Bootstrap 4 Modal. If I refresh and open the page, the modal backdrop will be normal. However, the modal backdrop opacity keeps getting darker and darker as I open other pages, I assume the opacity was not reset when Turbolinks loads in another page. I tried to find the backdrop element, but it looks like the opacity is generated on the fly by javascript. Has anyone seen the same problem? What’s the fix?

My guess is that you “killing” modal without closing it properly.
Modal backdrop is created for modal somewhere at the bottom of a page (outside the modal) and probably after some time you have collected several backdrops there that are making page darker and darker.

It’s a close normal way! but as I said getting darker!
