Confusing note about picture usage in elements#zoom when element is trashed

[rbjoern84]

Problem

When you go to pictures#zoom and look at the elements the picture is assigned in you will see no difference between available elements and trashed elements. The screenshot shows a trashed element:

This is confusing because when you click on a link of a trashed element you will be redirected to the page the element was rendered on but the element can not be found on the page because its in the trash. The problem is the user won't think of the trash. This gets annoying if you want to delete the picture in the library and you are looking for its element.

Expectation

1. In pictures#zoom you would want to see a note on the trashed element (where the picture is assigned in) that it is actually trashed.
2. When you click the link to the (trashed) element you should be redirected to the page but you should see the trash modal open with the highlighted element inside.

1. Easy
2. Extremely complicated

What about:

Only not trashed elements count as assignments? And pictures should be deletable if assigned to trashed elements.

If someone moves the trashed element back to the page the picture is not there anymore. In this case moving it back from the trash does not really make sense anymore.
