Sketchy table: Opaque background color hides inner cell borders and header background

[Mooninaut]

• Operating system: Windows 10
• Pencil version: 3.1.1

If I create a Desktop - Sketchy GUI Table shape, and set the background color opacity to 100%, the gray background of the header row, and the interior borders between cells are not visible. I believe this is because the table background is positioned above or in front of the header background and cell borders.

See attached screenshot. The bottom-right table demonstrates the bug.
