stack overflow when reading object tooltips causes debug session to terminate

my intention was to debug code which causes infinity recursion ;)
unfortunatelly it was in object ToString override;

instead i couldn't debug that code - vscode or omnisharp also went into that routine causes debug session to terminate:

how to reproduce:
```
class infinity {

public override string ToString()
{
return this.ToString();
}
}
class Program {
static void Main(string[] args) {

var inf = new infinity();
/* put breakpoint below, start debug session and move mouse cursor over inf object*/
Console.WriteLine(inf.ToString());
}
}
```
