FilteringSelect: onChange won't fire on changing to the first entry when displayedValue is set.

The use-case is a bit complicated, but you can check out the attached example.

I have a FilteringSelect? with some options. Because I want to make the user select one, I put a displayedvalue in there, that says "Unknown".
I added onChange to the FilteringSelect?, so every time the onChange event is fired, a alert shows up.
Now when the page is freshly loaded and the FilteringSelect? says "Unknown", I tried setting it to the FIRST option. But! The onChange event doesn't seem to fire here'''
The alert fires in every other occasion I have tested so far.

I saw this behaviour in 1.3.0 and 1.3.1.

The value attribute should have been set to something like "Unknown" as well.
