Error in Running Chrome Debug Instance when the Chrome window is open

使用列出的 React、Node.js、Chrome 和 Eclipse 步骤复现该故障，然后通过 ChromeAttachDebugDelegate.launch 以及堆栈跟踪中显示的 DSP 调试初始化过程追踪启动路径。比较关闭所有 Chrome 窗口时与存在一个 Chrome 窗口时的行为；当找到配置的 localhost URL 且调试在没有 about:blank 超时的情况下启动时，即表示完成。

When the Chrome window is open and I try to run Chrome Debug Instance, I get the error:

The application does not appear, and a blank tab is loaded, at the url "about:blank".

Steps to reproduce:

1. Create a react application:

npx create-react-app my-app
cd my-app

2. Create an Eclipse project in my-app folder.
3. Edit the file my-app/package.json adding the following line to the scripts key:

    "debug": "react-scripts --inspect=127.0.0.1:9222 start"

4. Start the application with the command:

npm run debug

5. Access the Eclipse menu:
   Run -> Debug Configurations -> Running Chrome Debug Instance

And create a new configuration.
6. Fill the URL field with: http://localhost:3000
7. Click in Apply
8. Click in Debug

When all Chrome windows are closed, the issue does not occur. However, it is bad to have to close Chrome every time we go to debug.
