Tab page headings get compressed on iOS

[lobbo232]

I have found an issue with tabbed pages on Xamarin that occurs on iOS.
I have enabled the plugin in AppDelegate with IQKeyboardManager.SharedManager.Enable = true;

My page is shown below. It is a tabbed page in Xamarin.Forms with a ListView that shows many rows, and a StackLayout below it with the text box.

When I click in the textbox, the keyboard works exactly as expected and the content is not overlapped any more. Great!

However, when the keyboard closes the tab page buttons at the bottom are also gone as shown here:

Xamarin.IQKeyboardManage: v1.4.1
Device: iPhone XS Max iOS 13.5.1
Xamarin: 16.6.000.1061
Xamarin.Forms: 4.6.0.762
Xamarin.iOS: 13.18.2.1

I have the same issue. My tabbed page doesn't completely go away but the tabbed page (menu icons) are cut in half so you can only see only about half of their height...
