[Bug]: Trying to add a "KTheme" Combo or List box to a form causes a "Universe not found exception

[Smurf-IV]

Using today's alpha branches from both repo's.

Open Designer for "KryptonListBox Example"
Drag a KComboBox onto form - Ok it does it
Drag a Themed KCombo or KListBox and there is a universe cannot be resolved error:
Win 10 22H2 latest

Using VS 17.11 p2.1

In VS 17.10.3 (and 17.9.6) then you also get an extra box thrown over the universe box:

Hi @Smurf-IV,

It's also with other controls, but not all.

The message can be removed by adding an "Assembly reference" to the project for System.Design.

It's also with other controls, but not all.

Hence the reason for this bug. Adding a designer to the Dev projects that uses Krypton should not be the solution.

Hi @Smurf-IV,

Ok, got it.

The designers/action lists are up for a review in V100, #1521.

ThemeCombo & ThemeListbox both inherit their designers and action lists from the KCombo & KListbox. These action lists expose properties that are unwanted for these controls. The KryptonStubDesigner exposes no action list and stops it from inheriting one. Only ThemeCBB and ThemeListBox are affected.

I tested a dummy designer that does nothing and derives from ControlDesigner.

    internal class KryptonStubDesigner : ControlDesigner
    {
    }

This removes the "universe" errors. Possibly can be used for other controls as well.

The ThemeCombo header is changed to this (KThemeListbox is similar of course)

    /// <summary>Allows the user to change themes using a <see cref="KryptonComboBox"/>.</summary>
    /// <seealso cref="KryptonComboBox" />
    [Designer(typeof(KryptonStubDesigner))]
    public class KryptonThemeComboBox : KryptonComboBox, IKryptonThemeSelectorBase

I'd like your OK on this before moving on?
And, please assign the ticket me, ty.
