Description

I am having some frustration trying to figure out (searching, trial and error) how to flush Plotly axis and the zero tick.

here is my code:

import plotly.go_objects as go

fig = go.Figure()
fig.add_trace(
    go.Scatter(
        x=x,
        y=y,
        name=label,
        mode="markers",
        marker=dict(size=10),
        opacity=0.5,
    )
)
fig.update_layout(
    font_family="Arial",
    template="simple_white",
    title={"x": 0.5, "y": 0.9, "xanchor": "center", "yanchor": "top"},
    yaxis=dict(mirror=True, ticks="outside", range=[0, 1]),
    xaxis=dict(mirror=True, ticks="outside"),
    legend=dict(
        yanchor="top", xanchor="right", borderwidth=0.5, x=0.995, y=0.99
    ),
)

Research direction

Start by reproducing the axis-tick alignment described in the issue using the provided Plotly graph configuration and compare the result with the linked Stack Overflow post. Trace the JavaScript axis and layout rendering entry points; done means the zero tick and axis ticks visibly align with the graph border without regressing other axis layouts.
