Previously, when editing a custom graph with multiple lines, the sticky table header at the top of the graph lines table appeared semi-transparent while scrolling causing graph rows to show through the header.

This has been fixed: the header is now opaque and stays on top of the rows, while per-row dropdown popups (e.g. for Line style) still open above the header as expected.
