TabBar have one extra focus Item on the last position - When tab between Items.

[rafael-rosa-knowcode]

What would you like to be added:

Using the TabBar, when navigating using the Tab, there is a last element that is not visible but receives the Tab focus.
The request is that the last element that is not visible does not receive the focus.

This is the Sample
https://playground.platform.uno/#89efac24

And this is the test case

  <StackPanel>
    <Button Content="Click and Start Here, than tab 5 times"/>
    <utu:TabBar Width="300">
      <utu:TabBarItem Content="Item 1" />
      <utu:TabBarItem Content="Item 2" />
      <utu:TabBarItem Content="Item 3" />
      <utu:TabBarItem Content="Item 4" />
    </utu:TabBar>
    <Button Content="Final, we lost one visible focus"/>
  </StackPanel>

Why is this needed:

This is to allow for more fluid navigation and without the user thinking that it is a failure of their application.
