Hi Florian, 

This is expected behavior. Third party does not persistent IDB storage, see https://bugs.webkit.org/show_bug.cgi?id=214583.

We used to not allow IDB in third party iframe and workers at all, and decided to add it for compatibility and match the behavior with localStorage. (Note different ports will be treated as different domains.)

Also, StorageAccess API does not work with IndexedDB yet. If it's important to you, you can file a bug for requesting support (something like https://bugs.webkit.org/show_bug.cgi?id=199105) and describing your use case. Feature request can help us understand what's needed by developers, and better schedule our work.
