1363 & MM3: Issue of drop-down-lists in skinned versions

[Friedrich]

The issue occurs in tracklistngs ("Show details"-view) and in the properties windows:

Skinned versions of MM4 & MM3:
Given: A drop-down field currently already contains a value.
The drop-down list positions at/shows the (alphabetically) first entry. Not the value currently in the field.
So one has to navigate down through the list to get to entries similar with the current one.

Non-skinned versions of MM4 & MM3:
When choosing a field with value "Barock" (genre) for example the drop-down starts/positions at the entry "Barock", showing all subsequent values, like:
Barock (current value)(highlighted)
Barock, Kantaten
Barock, Messen
Barock, Opern
etc.

I guess thats the way the drop-downs are intended to work.
Makes sense and saves lots of navigating through long lists.

Anyway, there is clearly a inconsistency in the behaviour between skinned & non-skinned version.
