Expected Behavior

The image should display as normal.

Actual Behavior

When you're handling a file:// protocol request, it's being treated like a regular URL. However, the file:// protocol is different from HTTP or HTTPS URLs in how it handles characters like #. In a file:// URL, the # character is typically part of the file or directory name and is not treated as a fragment identifier like in HTTP URLs.

Additional Information

If using the gist, the filepaths need to be updated in the renderer.js to actual images. The issue is when the image contains '#' in my case and I looked through the protocol.handle and saw it was treating it like a web request I believe where # usually means to truncate off the rest of the request. So it ends up trying to get an incorrect path item.
