SSIS Script Tasks losing code

Question

I have a very strange issue happening that is causing Script Task code to clear out. I have been able to test on 2-3 different machines. We are running SSDT 15.4 preview. The steps to reproduce were as follows.

1. Create a script task inside of a foreach loop container.
2. Create a comment in the script task.
3. Change or add a variable mapping in the foreach.
4. Save package.
5. Close the package.
6. Open the package.
7. Open the script task and the comment will have vanished.

As my last attempt for success,I have upgraded to 15.5.1 and the problem still exists.

If you close/Cancel the Script Task Editor form in Visual Studio after editing code, the code will not save. This will occur even if the code was saved in the other Visual Studio editor - the one where you edit the code.

You MUST click "OK" for the code to save.
