Even when a non-image file (say, a patch) is attached to an issue comment, it's still displayed as an <img>. We should have some checking mechanism that understands what type of file is being uploaded.
<img>
Right now, it looks like this, while ideally we should just display a link to the file. Opening the file works fine, though.
I believe @mreynolds added support for this and patch and diff are no longer treated as images.
Thanks for your report!
