Modal inside CMS stacking z-index issue

Hey! I have a modal inside a CMS list. When you click the list item, the popup modal should show up with info about the list item. However, because the modal is a child of the trigger (the list item) its higher z-value doesn’t make it stack on top of the list items. Therefore, the list underneath the modal shows through it.

Click the first list item “Borlänge” to try this, next to the map. So grateful for help.
