“实际上”带有（左）侧边栏主题的普通投影仪框架：脚注的垂直位置存在问题

我正在创建一个自定义的beamer框架“实际上”是简单的，带有侧边栏主题（PaloAlto）。

经过：

  • frametitle将的宽度设置为\paperwidth而不是\paperwidth-\beamer@sidebarwidth，
  • 利用\newgeometry，

我几乎成功了（“ right”PaloAlto也是如此），除了最后一个脚注行和页面底部之间的距离：它比普通（普通）框架更宽，如下面的 MCE 所示。

当然，我可以foot在新的几何图形中使用该选项，但我无法弄清楚所涉及的精确尺寸。

因此问题是：在这个定制的beamer普通框架中，如何使最后一个脚注行和页面底部之间的距离与普通（普通）框架相同？
