It started about a few days ago. I thought it was an error in my javascript, but I just tested with a completely blank app. There is a dropdown selector and a button. When the button is clicked it runs this line:
Appery('mobileselectmenu_4').val('Vici');
The highlighted item changes when the dropdown list is displayed in native mode, but the displayed "selected' item does not. The value returned by Appery().val() is correct, however.
I have verified this on 2 desktops, both Win8.1 and Win7, in both the newest IE and FF -- as well as the Appery Tester app on a Samsung Note 2 running Android 4.3
