Axis formatting not carrying over to hover text in shared axes

The code below produces subplots with shared Y axes (on the top row), then attempts to apply y axis formatting to display values in percentages. However, when hovering over the data points in the top right plot, I'm still seeing the default format instead of percentages. Wondering if that's intended, as I feel like the default behavior should be to apply the formatting to all the subplots with that shared axis.

from plotly.subplots import make_subplots
import plotly.graph_objects as go

fig = make_subplots(rows=2, cols=2,
                        specs=[[{}, {}],
                               [{"colspan": 2}, None]],
                        subplot_titles=("1", "2", "3"),
                        shared_yaxes=True,
                        horizontal_spacing=0.01,
                        vertical_spacing=0.15)

fig.add_trace(go.Scatter(x=[1,2], y=[0,1]),
                      row=1, col=1)

fig.add_trace(go.Scatter(x=[1,2], y=[0,1]),
                      row=2, col=1)

fig.add_trace(go.Scatter(x=[1,2], y=[0,1]),
                      row=1, col=2)

fig.update_yaxes(tickformat=',.1%')

Commencez par la reproduction Python fournie en utilisant make_subplots, shared_yaxes et update_yaxes, puis examinez comment y-axis tickformat est appliqué aux sous-graphiques partagés et aux libellés au survol. Le travail est considéré comme terminé lorsque les valeurs au survol du sous-graphique en haut à droite utilisent systématiquement le format de pourcentage demandé pour l’axe partagé.
