On delphi 10.1, the DPF TabBar Controller is not showing the tabs. if i rotate the device, them the tabs appear.
To reproduce the bug, create a new project on delphi 10.1 and put a DPF TabBar Controller and create two pages (set the page item titles to something). compile and launch the app. the tabs willl not appear. so, rotate the device from landscape to portrait or vice versa and then the tabs appear and become visible again. it does not matter if you start the app in portrait or landscape, it only shows the tabs if you change the device orientation. it worked ok on delphi 10, but this bug started on 10.1. tested using the latest DPF revision checked fresh from svn today.
