Shouldn't touch keyboard remain visible if Tab key on the touch keyboard
itself is pressed? Provided the next focusable component is a text
component, of course.
Consider the following scenario: start Notepad and open Replace dialog.
Touch "Find what" field: the touch keyboard appears. Press Tab on the
touch keyboard: the focus moves to "Replace with" field and touch
keyboard stays visible.
