Need to open popup relative to body

https://jsfiddle.net/mtqjewpx/

I have the container like the example above, pivot popups getting hidden, and needs to be scroll to view it.

I need to open the popup relative to body instead of pivot container. Is it possible?

I have one work around to achieve this, But is there any options that can be configurable in pivot option to achieve it .

Workaround:-

#fm-toolbar-wrapper div.fm-popup {
       top: 50% !important;
       left: 50% !important;
       position: fixed !important;
       transform: translate(-50%, -50%);
       z-index: 1001;
       max-height: 100vh;
       overflow: auto;
}

#fm-toolbar-wrapper div.fm-modal-overlay {
        position: fixed;
        height: 100vh !important;
        z-index: 1000;
}
