Can't download hex files in shared projects

[Amerlander]

In shared projects there are two buttons for editing. The gray one, which works fine and the button in the top right corner of the iframe. If some clicks on this button he isn't able to download the hex file afterwards.

To Reproduce Steps to reproduce the behavior:

1. Share a project

2. Open a new Browser or clear caches

3. Open the shared project url

4. Click on the "Edit" button inside the iframe

5. Click on "Download"

6. See how nothing downloads

Expected behavior In step 6 there should be a download.
