DarkComboBox disabled text color incorrect

[Kyle-Lancaster]

When DarkComboBox is disabled the text is still the same white color as enabled text, but it should be a darker grey color.

In DarkComboBox.cs

Line 117 add
var disabledColor = Colors.DisabledText;

Line 140 add

if (!Enabled)
{
textColor = disabledColor;
}
