Just wondering, does it happen only on HotReload? If so, won't it make the performance worse on release mode? Perhaps it should call this method only on DEBUG?

[StephaneDelcroix]

@felipemomm it can be reproduced by switching ViewCell.View, but no one ever done that before. the perf hit only applies when actually reassigning the View, and we just proved that no one does that, so it should be fine

There is a bug #6638 that can be related, it occurs in the ListView on iOS when the ReculceElement reuse the cell, changing the BindingContext. The BindingContext is changing, but the cell size is not.
And I think that after changing the BindingContext, perhaps need to call ForceUpdateSize too.
