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.

まず ns create my-tab-ng --template @nativescript/template-tab-navigation-ng を使って @nativescript/template-tab-navigation-ng のサンプルを作成し、次に iPhone SE 2 のような小さい画面の iOS 15 シミュレータで tns run ios を実行します。@nativescript/template-tab-navigation と比較し、あちこちクリックしなくても、初回のレンダリングで TabView が ListView を覆うことを確認します。
