[BUG] Toasts are broken

[comhar]

Describe the bug
Toasts are not displaying. The bug appears to have been introduced in this commit.

Minimal Reproducible Example
The app below should display a toast on load but it doesn't. If the inline dep is downgraded to the previous version python-fasthtml==0.12.24 then the toast displays as expected.

# /// script
# dependencies = ["python-fasthtml==0.12.25"]
# ///
from fasthtml.common import *

app, rt = fast_app()
setup_toasts(app)

@rt
def index(session):
    add_toast(session, "Successful Page Load!", "success")
    return P("I love toast!")

serve(port=5111)

Expected behavior
Toast should display.
