Grid only renders and lays out first child

Description

I have a Grid layout set as a Content to a ScrollView. Inside the Grid I have two children - the first one is not visible (IsVisible is set to false) and the second one is visible:

<ScrollView>   
    <Grid>
        <!-- If we switch the places of the two Labels the Text of the visible one will be visualized -->
        <Label Text="I am not visible" IsVisible="False"/>
        <Label Text="I am visible"/>
    </Grid>
</ScrollView>

When I run my application nothing is visialized. If I switch the places of the Children the visible child is visualized as expected.

Steps to Reproduce

1. Run the attached project.
2. Navigate to the second page.
3. Notice that nothing is visualized.

@hartez @PureWeen I thought someone opened this issue before - and I feel like that is why I know about it. But, I can’t seem to find it.

I am soooo sure I reviewed a PR on this exact issue that I am now doubting my memory.

If anyone knows of the issue, feel free to link to it.

Right now I am going to assume I can’t find the issue because it does not exist and will update the title to be more accurate.

@mattleibow Perhaps the bug is somehow related to how the Grid is measured by its parent. I assume the ScrollView measures the Grid with double.PositiveInfinity, while the ContentPage - with some fixed value. This is just a wild guess though.
