Previously, when editing a custom graph, dropdown popups in the graph lines table (e.g. Line style) were overlapped by the section headers (Graph lines, Graph Options) rendered below the table.

This has been fixed: the dropdowns now open above all surrounding elements as expected, and the earlier fix from Werk #19345 (header no longer transparent while scrolling) remains in place.
