Firefox moves the whole body to the right

This is weird. Firefox moves the whole body to right a little bit when opening the modal or when it's open.

Found the solution. This is because the modal is small enough so Firefox removes vertical scrollbars.
Solved by adding overflow-y: scroll but not sure if this should be prevented somehow in modal…?

This happens in all browsers, since the has-overlay class removes overflow-y in order to prevent the background-page from scrolling.
We need another solution for that where the overflow is not visible but the scrollbars are.

Will look into it soon.
