Getting crazy - Items bottom aligned in android

Hi I hope someone can help,

I’ve never had such a problem to align items to the bottom.

I’m using flexbox for that and our page has the following structure:

ion-header 
ion-content
   scroll-content // display: flex; flex-direction: column;
     ion-card // flex-shrink: 0;
     ion-card // flex-grow:1; flex-shrink: 0;
     ion-list

Both ion-cards should be top aligned and the list bottom aligned, which I could accomplish, BUT, in Android or MD mode, the list is not well positioned, see the print:

In Windows and iOS it is working fine, see print how it looks on iOS:

The most weird thing is: If I rotate to landscape and turn back to portrait, the issue is gone.

Does anyone has a clue or has faced something similar?
