autosizing issue since upgrade from 5.24.1 to 6.3.0

Since I upgraded plotly from 5.24.1 to 6.3.0 my diagrams do not take up the whole width of the parent container anymore.
Minimal working example using solara:

import solara
import plotly.express as px

@solara.component
def create_dashboard():
  fig = px.scatter(x=[0, 1, 2, 3, 4], y=[0, 1, 4, 9, 16])
  return solara.Div(
          [solara.FigurePlotly(fig)],
          style={"width": "100%", "display": "flex", "flex": "1 1 auto"},
      ),
  )

@solara.component
def Page():
    create_dashboard()

What is the accepted way of using full width in >6.0.0 ?

Start with the minimal Solara example in the issue and compare its autosizing behavior between Plotly 5.24.1 and 6.3.0. Trace how solara.FigurePlotly handles the figure container and determine what usage or change restores full parent width; done means the provided diagram fills its parent after upgrading.
