Feature request: show values of object properties on mouse hover while debugging

While debugging a Node application, hovering the mouse over a variable in the current scope will show its value in a popup. However, this does not work for variables' properties.

For example, hovering over a value named obj works, but not obj.propertyName, which instead just shows a documentation popup.

This means the only way to look up object properties is to use the Variables view, which can be cumbersome if a property is deeply nested (like obj.subObj.anotherSubObj.propertyName) or if the variable is in a nested scope (in which case you have to know/find the correct Block/Local/Closure scope that the variable resides in).

It would be helpful if the mouse hover popup could effectively do the work of digging through the Variables view for you.

首先跟踪现有的鼠标悬停弹窗行为，以及 Variables view 如何解析嵌套属性和作用域。使用 obj.propertyName 示例验证预期行为；当悬停时显示直接属性和深层嵌套属性的值，而不是文档弹窗时，即表示完成。
