[Bug] iOS gap on top of ListView when inside a shell tab

Description

If you have a data template with a list view inside a StackLayout or Grid, when that data template is used on a shell content in a tab, padding will be added on top of the list view which is not present when there are no tabs.

Steps to Reproduce

Create a xamarin app with a Shell as the main page
Create a data template with a StackLayout containing a ListView
Add a FlyoutItems element
Add a ShellContent element with the ContentTemplate set to the created template
Add a Tab with multiple ShellContent elements inside, using the same data template

Expected Behavior

The contents of all the pages should look the same

Actual Behavior

There is padding added on top of the list views that are inside the Tab element.
