Shell Tab is still visible after set Tab.IsVisible to false

[SamShanWang]

Description

In the beginning, there is one tab visible ( tab 1 ) and two tabs hidden ( tab 2 and tab 3 ) on a TabBar. Then I want to display tab 2 and tab 3. Meanwhile, hide tab 1.

1. Here is the code to do it.

Tab2.IsVisible = true;
Tab3.IsVisible = true;
Tab1.IsVisible = false;

Run in Android platform, the result is:

If you tap 'Tab 3' tab header, the app will crash.

When run in Windows platform, the result is correct.

2. If I use the code below.

Tab1.IsVisible = false;
Tab2.IsVisible = true;
Tab3.IsVisible = true;

Then run in Android platform, the result is correct.

But run in Windows platform, the app will crash.
