The specified argument is outside the range of valid values

I very rarely get the following error. It appears to self-resolve making me suspect it is intermittent based on something outside of the document being written. But I am really not sure, any suggestions apprechiated.

Yep, the bug is in that code, here is a test. It fails on i = 123.

    [Fact]
    public void EscapeGrowBug()
    {
        for (var i = 0; i < 1000; i++)
        {
            var obj = new JsonObjectSmall { N = new string('"', i) };
            var result = JsonSerializer.Generic.Utf8.Serialize(obj);
        }
    }
