It does not make any difference how sticky sidebar configured. You will always see only part of it if it is too long. Do you agree? 😄
Any way, there are two ways how and when it sticks. The one, you find the right one. And the one, I would like to achieve. The second one is not possible with ipsSticky. Sure, it is possible with external coder 😄 and custom code. But this is not what I have asked for. I have asked, if the behaviour I wish can be achieved with ipsSticky. Obviously not. 😉
