Incorrect Content-Type being applied to uploaded files in v 4.4.0

[okadots]

Describe the bug

When uploading files via the WP admin, the Content Type is being incorrectly applied in Azure. All files, regardless of file type, are being uploaded to Azure with the content type of application/octet-stream.

In WordPress, the attachment details show the correct content type.

This is causing PDFs to automatically download vs open in the browser. This is the case for all uploaded media files as well.

Changing the content type via the Azure interface resolves the behavior issue, but manually resolving for every file uploaded to a multiuser multisite is not a reasonable workflow.

Downgrading to v 4.3.5 fixes the issue and the correct content type is applied.

Steps to Reproduce

1. Upload a file of any kind via WP admin
2. In the attachment details, copy the file url and paste in browser. File will download instead of being viewed in the browser.
3. To test file type, curl -v the file url and see that content type is: Content-Type: application/octet-stream
