Steps to reproduce:

• Select some component in Navigator
• Click + in Properties view - Local custom properties
• These types are available:
  • int
  • real
  • double
  • color
  • string
  • bool
  • url
  • alias
  • signal
  • TextureInput
  • vector2d
  • vector3d
  • vector4d
• Open Connections view - Properties
• Click +
• These types are available:
  • int
  • bool
  • var
  • real
  • string
  • url
  • color
• -> There are more types available from Properties view (bolded in the above listing).
• -> Type "var" is only available from Connections view
• Would expect available types to be the same regardless from where user creates custom properties.
