Can not show terminal inputs when break `readline()`

Environment

• OS and version: Windows 10
• VS Code: 1.77.3
• C/C++ extension: v1.15.2
• OS and version of remote machine (if applicable): Ubuntu 22.04
• GDB / LLDB version: GNU gdb (Ubuntu 12.1-0ubuntu1~22.04) 12.1

Bug Summary and Steps to Reproduce

Bug Summary:

When use readline() and break(Shift + F5 or Ctrl + C) the program, terminal will not display inputs. (But still can execute commands).

Steps to reproduce:

1. create echo.c:

#include <stdio.h>
#include <readline/history.h>
#include <readline/readline.h>

int main() {
  char* line = NULL;
  while (line == NULL || strcmp(line, "q") != 0) {
    line = readline("> ");
    printf("%s\n", line);
  }
  return 0;
}

2. Press F5 to debug program.
3. Press Shift + F5 or Ctrl + C .
4. cppdbg terminal will not show inputs.
5. Inputs will display normally if enter q.

Additional Information

No response

Reproduce the issue with echo.c using the shown launch.json and task.json, then interrupt the readline() session with Shift+F5 or Ctrl+C and compare terminal input rendering before and after entering q. Start by tracing the cppdbg terminal and debugger interruption path; done means inputs remain visible after interruption and the behavior is covered by a regression test.
