Description

Issue seen in openedx/frontend-app-admin-portal. With this PR that allows consumer to configure the overflow in a ModalDialog, we observed a bug where you are now unable to scroll. The actual code here is using a FullscreenModal, and I've included in screenshots what the previous scroll behavior was. Setting 'isOverflowVisible' to false fixes the scrolling issue, but this bug is effecting every modal.

Research direction

Start with the linked consumer code in src/components/PeopleManagement/CreateGroupModal.jsx and review the referenced Paragon PR 2939, then trace how FullscreenModal handles isOverflowVisible. Reproduce the scrolling behavior in a modal and confirm that the corrected behavior applies to affected modals without disabling the intended overflow configuration.
