ScrollView with Fill vertical option is bigger than the page when ScrollView is a root on iOS

[cucumber-sp]

Description

When ScrollView (or ScrollView inside RefreshView) is a root of Content page, it doesn't handle Height correctly. When you set VerticalOptions to Fill (when inside RefreshView it's always Fill) it takes more space than the page size. When you set Start option it makes ScrollView even smaller than its content.

VerticalOptions="Fill" (content of scrollView starts at the title, it's not a padding)

VerticalOptions="Start"

Grid is the root of page, everything works fine
