Colorbar is not showing last tick

Hi,
I have added a horizontal colorbar to a heatmap figure and can't get the last tick to show. Here are some of things I tried and thought are the most logical:

colorbar= dict(
            orientation='h',
            y=1.01,
            tickformat=".0%",
            tickmode='array',
            tickvals=[0, 0.25, 0.5, 0.75, 1],
            showticksuffix='last',
            ), 

and

colorbar= dict(
            orientation='h',
            y=1.01,
            tickformat=".0%",
            tickmode='linear',
            tick0=0,
            dtick=0.25,
            nticks=5,
            ticklabeloverflow="allow",
            ), 

but both yield the same result:

I have also tried moving the bar around the x axis and played with labels and length, but it always seems missing.

Is this a bug?

Plotly: 5.24.1 and Python: 3.12.7

使用 Plotly 5.24.1 和 Python 3.12.7，通过提供的 tickmode='array' 和 tickmode='linear' 配置复现水平热图 colorbar。跟踪 colorbar 如何处理最后一个 tick，并确认 1.0 tick 标签能够渲染且不影响其他标签，以验证修复。
