Issue Summary

As a Confluence administrator, you can upload an image to become the site favicon through the Site Logo and Favicon option.

While trying to upload an image that has been manually converted from the following specific formats as the site's favicon, an error will be displayed:

Steps to Reproduce

1. Manually edit an image file's extension from .ico to another format or vice-versa (by editing its extension).
2. Save the image locally.
3. As an administrator of Confluence, tap the cog icon at the top right.
4. Select Site log and favicon from the sidebar
5. Upload the converted image.

Expected Results
