Steps to reproduce

compile this code in c++ and run it.
go to task manager --> open terminal group processes --> program.exe --> go to details
click the x button on windows terminal.
the process of program.exe is no longer running and if you insert a while loop in the handler it closes 5 seconds later. This bug is reproducible with cmd powershell and conhost and windows terminal. I don't know which program issue or issues its on so I am reporting it here

BOOL WINAPI controlHandler(DWORD sig)
{
	if(sig == CTRL_CLOSE_EVENT)
	{
		Beep(800, 500);
		FreeConsole();
		return TRUE;
	}
}
int main()
{
   SetConsoleCtrlHandler(&controlHandler, TRUE);
   while(true);
}

Expected Behavior

the process to stay open

Actual Behavior

process closes

The issue names no repository file or test. Start by reproducing the provided C++ CTRL_CLOSE_EVENT handler with Windows Terminal, cmd, PowerShell, and conhost, then determine whether the five-second termination is terminal-specific or Windows API behavior. Done requires identifying an actionable terminal-side change or documenting that the behavior is outside this repository.
