Feature-Request: Help to locate the source position from where a network request was made

When optimizing network performance in a big app it would be helpful to see in the network page from which line of code a certain request was made including a stack trace.
Thinking more on this, that is probably not possible because you would have to store a lot of stack traces.

But perhaps it would be an option to select request in the list and have a new function 'break on next request like this` that would make the app break so that the current stacktrace before the actual request is made could be inspected,

未指定任何文件或测试。首先定位网络页面和请求处理入口点，然后评估如何让选定的请求在下一个匹配的请求之前触发暂停。完成的标准是：从选定的网络请求出发，下一请求暂停工作流已定义并且能够正常工作。
