i have problem with ion-scroll and orderBy filter. When the item in the list is changed and orderBy is fired the scroll element move its position to the top. I created a plunker for better understanding: https://plnkr.co/edit/Bl6wQZZsJh0rOsRaK6WO?p=preview
In this plunker when you uncheck checked item there is no problem, however if you check unchecked item it causes the problem.
I will be happy for ever help.
