DescriptionsplitPane's handle uses a zIndex of 2 to be on top of the iframe. That causes the handle to hover over other elements. As the iframe is hidden (with z-index -1) when not dragging the handle, the handle z-index can revert to default (0) when not dragging and hover only while dragging, which solves the problem of having two dialogs with a splitPane in them.
