iOS app on M1 Mac: shortcuts bar above keyboard only shows gray bar for text editor in WKWebView

Our app hosts a rich text editor inside a WKWebView which is focused automatically. On iPhone and iPad the shortcuts bar above the keyboard is shown correctly with up/down arrows and the "done" button.

When running the iPad app on an M1 mac the bar is just gray without any buttons. If the focus is removed from the webview and refocused the shortcuts bar is shown correctly.

Is this a known issue

The app was built with Xcode 12.5.1

Any progress?
