Description

Description

In some Entry fields the keyboard is closing on every key stroke. This problem was introduced since Xamarin Forms 3.0. So in 2.5 this problem didn't occur.

The problem only occurs when the controls are in a TableView.

This problem only occurs in iOS, not Android (afaik). I've tested in iOS 12.0, 12.1.

Steps to Reproduce

Use the attached test project.

On an iPhone SE screen size, the problem occurs in entry field number 10 and 11, at least in my test scenario. If you use an other iPhone with a larger screen size, like XR, the problem occurs in other Entry controls, lower in the screen (> control no. 11).

Expected Behavior

Keep the keyboard open.

Actual Behavior

Keyboard closed on every key stroke.

Research direction
Investigate the interaction between TableView and Entry controls on iOS. Check for any changes in Xamarin.Forms 3.0 that might cause the keyboard to dismiss on each keystroke. Look at the TableView's handling of focus or scroll events.
