In model comparison mode, only the reference model appears to be added to URL

[rdnfn]

The main model (annotator) does not appear to always be added to the URL.

Steps to reproduce:

1. Go to https://app.feedbackforensics.com/?data=arena_special&ref_models=llama4maverickopenrouter&analysis_mode=model_analysis
2. Add Llama-4-Maverick-03-26-Experimental as main model, click run analysis
3. Now check the link: the model selected in step 2 does not appear.

EDIT: Note likely cause: the data dictionary is not fully updated with the model annotator before generating the URL inside the load callback.
