When I have a listView in a component, and I press home button to background the app, sometimes when I return, the heights of all my rows are collapsed.

This is a small test I made:

Code:

 <GridLayout rows="*"> <ListView [items]="temp_items"> <ng-template let-item="item"> <StackLayout height="100"> <Label [text]="item.title"></Label> </StackLayout> </ng-template> </ListView> </GridLayout> 

Expected:

Reality:

The only way I can get it not to break is if there is a height AND width on the GridLayout or ListView. There must be both height and width: just one or the other won't do. This is impractical, though, because most of the time it is preferable for ListViews to resize dynamically and fill the screen.
