Test Project

## Description

Starting from a new Android Single View project, if I create three new layout folders with qualifiers and copy the Main.axml layout file to all three new layout folders, when I open the layout file, switch to the Source tab and then back to the design tab, the layout does not render and will not render again until VS is restarted. then the layout will render once when initially loaded but will not render again after switching to source tab and back to design tab.


## Steps to reproduce 

1. Open the attached test project in Visual Studio 2017 Windows (already has the layout folders added and the layout file in 3 of the 4 layout folders)

2. Open the Main.axml file into the Android Designer

3. Switch to the source tab and then back and note that the layout renders.

4. Closer the Main.axml layout file

5. Copy and paste the Main.axml layout file into the layout-sw600dp-land folder

6. Open the Main.axml file into the Android Designer

7. Switch to the source tab and then back

Expected result: layout will render.

Actual result: layout does not render.
