I think there is an Issue with the TextInput.
The text (text property) inside the TextInput is cut off , when you have been navigating from a side menu, which is itself animated by a drawer. The SideMenu is on left Side and the text is cut on the right side.
So only the first part of the text is visible. When tapping into the TextInput all the text appears and stays.
This happens only when comming from opened Menu and only on Device, not on emulator.
