When I open product design in lightbox: If the scroll is on the top of page, I can see the toolbar and use it easily (Look at the first image). But, If the scroll is in the middle of page, I can't see the toolbar (Look at the second image). In order to see the toolbar I have to scroll to the top of page.
It makes my customers confuse when they open product designer in lightbox. How to fix it? Thank you in advance.
