Ignore roads outside of working area

I think this is a regressions as I don't think it happened before.

For example if I define my neighborhood with those boundaries :

LTN will show lots of "outbound facing" cells on the periphery :

I guess the black dashed line has something to do with it ?

该问题是 LTN 工具在定义的邻域外围显示带有“outbound facing”标记的单元格。查找处理边界定义和单元格渲染的代码，可能位于与地图可视化或邻域分析相关的模块中。检查最近是否更改了对工作区域外道路进行过滤或显示的方式。使用提供的示例边界运行该工具应该能够复现此问题。
