I noticed odd behavior of the uieditfield background color property - it is affected by its parent background color, as shown in the following example.
In all three case, the background color of the uieditfield object is set to 'black'. As it can be seen, the displayed background color is affected by its parent background color. I suppose this has something to do with opacity/transparency, but it seems that uieditfield does not have this property.
How can I get pure BLACK background color in all three cases?
Please find attached the minimum working example.
