Thanks for submitting this fix.

One thing I would change would be that if the text lookup fails, I think it would be better to fall back to the first letter of the severity code as the icon instead of just letting it be blank.

Yes, it looks like it is. Sorry I didn't remember about that as I was reading the changes.
