When combining Plotly plots using subplots, the middle plot shrinks

When combining Plotly plots using subplots, if ncol is 2 and nrow is greater than 2, the height of the middle row is smaller compared to the top and bottom plots. Similarly, if nrow is 2 and ncol is greater than 2, the height of the middle column is smaller compared to the first and last plots. This discrepancy occurs because the margin values are not applied consistently; the top margin value is not applied to the top plot, and the bottom margin value is not applied to the bottom plot. Is there any workaround to get all plot in same height

该 issue 没有指明文件、测试或入口点。首先复现 ncol 和 nrow 大于二时 subplot 高度不相等的问题，然后跟踪 subplot 边距的计算和应用方式。完成的标准是：在保留所请求边距的同时，各行或各列具有相等的绘图高度，并且两个情况都有回归测试覆盖。
