claude .TokenUsagePercent doesn't work with `background_templates`?

What happened?

I'm observing color template statements like {{ if gt .TokenUsagePercent 50 }} don't work at all.
I think the Go template is correct because {{ if gt 100 50 }} works just fine.

Repro:

- type: claude
  style: diamond
  powerline_symbol: 
  trailing_diamond: 
  template: " Context: {{ .TokenUsagePercent }}%/{{ .ContextWindow.ContextWindowSize }}"
  foreground: "#f8f8f8"
  background: "#273c75"
  background_templates:
    - "{{ if gt .TokenUsagePercent 50 }}#eccc68{{ end }}"
    - "{{ if gt .TokenUsagePercent 70 }}#ff6348{{ end }}"
    - "{{ if gt .TokenUsagePercent 85 }}#ff4757{{ end }}"

Version: 29.1.0 (latest).

@ahmetb I do need the logs though, the template rendering is in there. You can enable tracing by adding the --trace flag to the oh-my-posh claude command. The logs can be found inside the logs folder at oh-my-posh cache path.
