I'm trying to keep scrollbar visible but disable scrolling while the image is in the front.

lightbox2.option({
   disableScrolling: false,
})

I'm using this option from the Lightbox2 library but this also hides scrollbar.

Use case: When an image is opened in this library, all content of the page is moved a little bit to right because the scrollbar dissapears. I want to disable this unwanted movement.

Is there any way how to do it quickly ? Or at least how to find out if the library is currently activated (image is in front) ?
