iOS 7: ListView - SearchBar disappears on device rotation if there are no text in the SearchBar

Details: If you add a SearchBar to a ListView, scroll up on the list until SearchBar (no text) is not visible, rotate device, then the SearchBar will disappear if you scroll back to the top.

Note:
1. This is not a regression as this occurs in both SDK 3.2.2.GA and 3.2.3.
2. This does not occur with iOS 6 devices.
3. SearchBar will re-appear if you rotate the device again.
4. If SearchBar disappears and you press on the empty area (see empty.png), then the SearchBar will re-appear again and persists regardless how many times you rotate the device afterwards.

Steps to reproduce:
1. Create a default Classic app with the app.js attachment and include these orientation in tiapp.xml:

<key>UISupportedInterfaceOrientations~iphone</key>

<array>

    <string>UIInterfaceOrientationPortrait</string>

    <string>UIInterfaceOrientationPortraitUpsideDown</string>

    <string>UIInterfaceOrientationLandscapeLeft</string>

    <string>UIInterfaceOrientationLandscapeRight</string>

</array>

<key>UISupportedInterfaceOrientations~ipad</key>

<array>

    <string>UIInterfaceOrientationPortrait</string>

    <string>UIInterfaceOrientationPortraitUpsideDown</string>

    <string>UIInterfaceOrientationLandscapeLeft</string>

    <string>UIInterfaceOrientationLandscapeRight</string>

</array>

2. Launch app onto device
3. Press on List w/ Search tab
4. Scroll up on ListView until SearchBar is not visible
5. Rotate device in any direction
6. Scroll down on ListView until you're at the top

Actual: SearchBar is missing (see empty.png).
Expected: SearchBar should not disappear (see expected.png).
