Empty space appears above TabBar after navigating back when TabBar visibility is toggled

[janeqDev]

Description

I’m using Shell with a TabBar. One of the tabs contains a page with a ScrollView.
When navigating from this page to a details page, I hide the TabBar by setting Shell.TabBarIsVisible="False".

After navigating back to the original page, an empty space appears above the TabBar.
It looks like the ScrollView height is recalculated incorrectly, as if the scrollable area is shortened and leaves unused space above the tabs.
