Can't get Oh My Posh foreground_templates to work for 'text' segment - oh-my-posh

Question

I cannot seem to get foreground_templates to work for a text segment. Below is the last block of my prompt.
If I am running with normal privileges, I should see just a green "crescent moon" prompt character. If I am running with elevated privileges, I should see a red pill with an "unlocked" icon, followed by a space, then a red crescent moon prompt character.
The {{ if .Root }} template in the text property to add the additional space works. The {{ if .Root }} template in the foreground_templates does not work. No matter what I try, I always get a green crescent moon.
I can work around it using template coloring in the text property, but it is quite a bit uglier:
"text": "{{ if .Root }} <lightRed>\uF5DA</>{{ else }}\uF5DA{{ end }}"
I can't spot anything wrong. Can you?
