"Hit test at this location" feature

I was trying to figure out where a hit test was going (I'm writing a test, and tapping is not hitting the node I am identifying with the finder).

The "select widget" feature, amusingly, finds the node I am aiming for when I tap.

It would be useful to have a feature where you could tap the screen and instead of selecting a node, it gave you a list of the nodes that were hit, with the ability to jump to each of those nodes in the inspector.

This is probably a low-priority feature request.

首先检查 issue 中提到的现有“select widget”功能，并复现报告的点击与 finder 之间的不一致。将 hit-node 列表和 inspector 跳转行为定义为完成标准；issue 未列出任何文件或测试，因此定位这些入口也是工作的一部分。
