Uploading unsupported file types to New Quizzes breaks the download link

[#1]

This behavior has been resolved and deployed to the production environment as of 1/28/25.

Description

When uploading an unsupported file type file to a New Quiz question, the download link for the file changes, the file name is dropped during the download process, the hash for the file is used as the downloaded file name, and the file extension is dropped.

Expected Behavior

Instead it should allow the file to be downloaded in the same format that it was uploaded.

Workaround

Provide a link to a course page where the files are linked in the quiz question so users can download the files from there.

Steps to Reproduce

Prerequisite: Have a course with a new quiz in it

1. Go to the build page for the New Quiz

2. In a new question select the upload document option from the RCE

3. Select an unsupported file type, I used zip files

4. Save the quiz and refresh the New Quiz page

5. Preview the quiz and click the link to download the file

6. See that the files name has changed and no longer has an extenstion
