[Bug]: Exception at design time When Assigning CustomPalette to PropertyGrid / TreeGrid

[tobitege]

Exception during design time

"Specified argument was out of the range of valid values.
Parameter name: ContextNormal"

To Reproduce

• Added to the TestForm -> TreeView example form a KryptonCustomPaletteBase (customPalette) as well as a KryptonManager component.
• No changes done to either components yet.
• In properties of the manager switched the "GlobalCustomPalette" to "customPalette" and the exception occured.
• The GlobalPaletteMode was still default of "Microsoft 365 - Blue" at that time.
• Also tried switching the latter to "Custom" and then GlobalCustomPalette to the new palette component, but again an exception:

Expected behavior
No exceptions if possible. :)

Screenshots

Desktop (please complete the following information):
