Test the file name in the download dialog

Download an image from the preview and read its name in the save dialog. Check the folder where it lands, too. A name that makes sense in the export list can still turn into something generic on disk.

Use two versions of the same image for the test. A suffix such as print proof or small preview should let someone pick the right file from the download folder without opening both. If the suffix goes missing, include the filename you actually received when you report the issue.
