TabView transparent under iOS 15

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 8.1.1
• Cross-platform modules: 8.1.3
• Android Runtime:
• iOS Runtime: 8.1.0
• Plugin(s): -
• NativeScript-Angular: ^12.2.0
• Angular: ^12.2.0

Describe the bug

The TabView is transparent on first render and only gets initialised correctly after some clicking around.

To Reproduce

Setup:

ns create my-tab-ng --template @nativescript/template-tab-navigation-ng

Run:

tns run ios

Make sure you run a iOS 15 simulator with a small enough screen, e.g. iPhone SE 2.

Expected behavior

TabView covers ListView elements.

Sample project

@nativescript/template-tab-navigation-ng

Additional context

It seems to be an nativescript-angular problem since the @nativescript/template-tab-navigation is not affected.

首先使用 ns create my-tab-ng --template @nativescript/template-tab-navigation-ng 建立 @nativescript/template-tab-navigation-ng 範例，然後在螢幕較小的 iOS 15 模擬器（例如 iPhone SE 2）上執行 tns run ios。將它與 @nativescript/template-tab-navigation 比較，並確認 TabView 在首次轉譯時會覆蓋 ListView，而不必到處點擊。
