cannot set breakpoints and debug the client source codes one line by one line correctly

[woxingren]

I open the folder and try to debug the client source code. But I cannot set a breakpoint at the specified line and debug the client side source codes one line by one line correctly. There is always a few lines difference between the line of code the cursor is set to and the real line of code I am debugging. There is no issue to debug the server side source code.
