Ionic/angular > 4.11.6 Scroll broken

There are currently 2 issues with scrolling. The second one has been introduced newly, the first one has been here for years:

  1. All latest ionic versions have a bug in the scroll behaviour.

When switching from 1 page to another, after the second page has finished loading, it also scrolls down to the same height as the previous page is:


Is reproduceable here:

  1. Also noticable in the ionic conference app, when going BACK it doesnt store the scroll position.
    Its a few years now with this bad behaviour, is there any better workaround that storing the position manually on leave and scrolling to it on init?
