Export dependency resolution missing optional dependencies

Have an app that uses pandas which has an optional dependency on Jinja2 for styling the tables.

When exporting this application, the jinja2 dependency is missed unless imported explicitly.

minimal reprex:

# explicit import of jinja2 required for shinylive 0.0.7?
# fails on viewing static site result of shinylive export
# if this import is commented out, fine if import is there
# import jinja2

import pandas as pd
from shiny import ui, App, render

app_ui = ui.page_fluid(
  ui.output_table("table")
)

def server(input, output, session):
  @output
  @render.table
  def table():
    df = pd.DataFrame({"a": [0,1], "b": [0,1]})
    return df
  
app = App(app_ui, server)

Start by reproducing the minimal pandas and Shiny application with a shinylive export, comparing the result with and without the explicit jinja2 import. No source file or test is named in the issue; done means the exported static site works without that explicit import and the regression is covered by an appropriate test.
