React-modal: Border appears when modal opens. Only when using className instead of inlineCss

[shmekla]

Summary:

Hello, I ran into a problem using react-modal. Whenever I add a className, the weird border appears when modal open. Doesn't appear if I use inline, but I need responsiveness, that inline doesn't provide.
It disappears when you try to inspect or click on inspect panel.
Anyone else ran into this issue?

Steps to reproduce:

1. Using CSS classes for styling (Official demo)

Expected behavior:

That weird border, shouldn't be there.

@shmekla
Are you talking about the border around the modal itself? It might be because the whole modal is in focus.

:focus { outline: none; } removes it.
