Bug TouchScreenKeyboard is considered Visible when Status is LostFocus

When you display the touch keyboard, and click outside of the keyboard area to close it, the status is set to LostFocus as Expected, but visible stay at TRUE.

Is there any reason for that? When it happen you need to double click on the input field to reactivate it.

If you click on OK and have a STATUS of DONE, then visible will be set to false, and single click on input field will work

Also is it normal that in TMP_Input, the Status = Visible is never trigger?
