Test case

Switching to Design tab before undoing Source changes adds android:entries attribute to Spinner elements

This problem happens both in Xamarin Studio and in Visual Studio on Windows. So far I haven't found a way to reproduce it in Xamarin Studio on Mac, but it might happen there too.


## Steps to reproduce

1. Open the `Main.axml` layout from the attached test case in the Android designer.

2. Switch to the Source tab.

3. Copy and paste the XML contents of the layout over itself.

4. Switch back to the Design tab.

5. Save the document.

6. Select "Edit -> Undo".

7. Save the document.

8. Switch back to the Source tab.



## Result

Compared to the original, an `android:entries` attribute has been added to the `Spinner` element:
> android:entries="Item 1"



## Expected result

No extra attributes are added to the `Spinner` element.
