Why does my popup hide under under page elements and is not fully visible?

This might be due to a z-index issue.

z-indexes on websites help a browser understand which elements live in which layer of the page. Popup naturally is expected to appear on top of all other elements.

Please see this article for possible solutions: Other Page Elements on Top of Popup
