No stdout and stderr while debugging with gdbserver

Type: Debugger

Describe the bug

• OS and Version: Ubuntu 20.04
• VS Code Version: 1.48.2
• C/C++ Extension Version: 0.29.0
• Other extensions you installed (and if the issue persists after disabling them):
• A clear and concise description of what the bug is

I have a launch configuration to connect to gdbserver running inside docker.
Everything works well, I can set breakpoints and see variables, but I don't get any output at all, not in the "output" panel and not in the "debug console".

I tried changing "externalConsole" as I saw in other issues, but it didn't help.

My launch.json file:

{
	"version": "0.2.0",
	"configurations": [

  {
			"name": "C++ Launch (GDBSERVER)",
			"type": "cppdbg",
			"request": "launch",
			"miDebuggerServerAddress": "localhost:2000",
			"preLaunchTask": "start-gdbserver",
			"miDebuggerPath": "/usr/bin/gdb",
			"targetArchitecture": "x64",
			"program": "reassembly",
			"args": [],
			"stopAtEntry": false,
			"cwd": "${workspaceRoot}",
			"sourceFileMap":{
				"/home/develop/project": "${workspaceRoot}",
				"/usr/include/c++/9.3.0": "/usr/include/c++/9"
			},
			"environment": [],
			"externalConsole": false,
	}
 ]
}

Empieza reproduciendo la configuración launch.json proporcionada con gdbserver ejecutándose en Docker sobre Ubuntu y, a continuación, observa el panel Output y la Debug Console mientras se ejecuta el programa. Compara el comportamiento de stdout y stderr con la salida esperada del depurador; estará terminado cuando ambos flujos sean visibles durante la sesión de depuración de C++ de VS Code.
