Why EditorBrowsable doesn't work?

Question

I tried to hide inherited property in intellisense with EditorBrowsable (as said here Hiding user control properties from IntelliSense), when testing in client form though I can still see it why ?

[
Category("Main"),
Description("Text"),
Obsolete("Don't use this"),
Browsable(false),
EditorBrowsable(EditorBrowsableState.Never)
]
public override String Text
{
    get { return null; }
}

Answer 1

I repro. There is a Note in the MSDN article about this:

In Visual C#, EditorBrowsableAttribute does not suppress members from a class in the same assembly.

Oddly, I don't see it suppress it either when I put the UserControl in a different assembly in the same solution.
You may want to ping connect.microsoft.com about this, something isn't right.
