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 创建 @nativescript/template-tab-navigation-ng 示例，然后在屏幕较小的 iOS 15 模拟器（例如 iPhone SE 2）上运行 tns run ios。将其与 @nativescript/template-tab-navigation 进行比较，并验证 TabView 在首次渲染时会覆盖 ListView，无需到处点击。
