pcbnew 3D viewer: having 'use board stackup colors' selected disables viewport background color edits
Description
The viewport 'background start' and 'background end' colors cannot be edited while the 'use board stackup colors' box is checked. These colors aren't actually set by the stackup and disablig the check mark, setting them, re-enabling the check does keep the changed background.
