Autocompletion prioritizes more distant entry

Steps to Reproduce:

class Program
{
    class MyClass { }
    static void Main()
    {
        MyClass myClass;
        mycl|
    }
}

Expected Behavior:
myClass be preselected, it differs in only one letter casing. (I would also expect the first letter to be more important when ambiguous.)

Actual Behavior:
Once you type c, the preselection changes to MyClass, although it differs in two letters:

Even if the current scoring makes them equal, that should not be enough to change the existing preselection.
