Titanium 3.2.3 causes unwanted soft keyboard in Android WebViews

I have an Alloy app built using Ti 3.2.2.GA that works well in all tested versions of Android. It includes windows that contain WebViews.

Upgrading to use Ti 3.2.3.GA, on Samsung phones (and possibly others), opening any window that contains a WebView causes the soft keyboard to appear. Any combination of the following does NOT hide the keyboard:

Ti.UI.Android.hideSoftKeyboard();
    $.details.softKeyboardOnFocus = Ti.UI.Android.SOFT_KEYBOARD_DEFAULT_ON_FOCUS;
    $.details.softKeyboardOnFocus = Ti.UI.Android.SOFT_KEYBOARD_HIDE_ON_FOCUS;

Any ideas?
