Declining a package instantly logs you out of silanis. Why?

In our software we generate a package in the background then display an IFrame to the URL created with the package from the .net SDK. Right now I have only seen this in your sandbox. If you sign the package normally everything works fine but if you decline or opt-out we get the a screen that says the following: Your browser need to have cookies fully enabled. Possible reasons below:

• You might have third parties and advertisers options enabled
• Cookies are disabled
• Your Login Session has expired

To enable cookies, follow these browser-specific instructions.

• Safari > Preferences, and then click Privacy
• In "Block cookies and other website data" section, specify Safari should accept cookies from this website
If you have cookies enabled but are still having trouble, clear your browser's cache and cookies 1) This is saying browser specific and shows Safari info but I was using IE 2) I know cookies are enabled because our website requires them, without them I would have authentication issues in our site With this information I decided to create a package and just open it in a new window. When I declined the package it instantly took me to a log in screen. I had to refresh the URL to get a confirmation saying that the package was denied. Why does declining or opting out of a package instantly sign you out? This is an issue because if a user declines a package we don't want them seeing a silanis error screen when there was no error.
