Basket feature is broken

[sebastian-meyer]

• When adding an item to the basket, you get redirected to the basket view. But there is no way to get back to the page you came from (other than using the brower's back function, which causes other problems). I'd expect to not get redirected to the basket instantly or at least be able to return to the previous page.
• If you click on an item in the basket, the basket get's duplicated in a separate tab. I'd expect to get redirected to the page view showing the clicked item instead.
• The download function doesn't work. A loading indicator appears for a second, but nothing happens.

Thus the basket feature currently is completely broken as you can't do anything with the items you added to the basket. They are just there, but cannot be downloaded or viewed again. The only way to get out of the basket view is to return to the homepage and start all over again by clicking on the Kitodo.Presentation logo.
