…1087)

If the virtual keyboard should not show automatically, then the input
method mode should be set physical keyboard when the user closes
the virtual  keyboard by interacting with the virtual keyboard itself.
For example, if the user clicks a close button in the virtual keyboard
or clicks an icon in the task bar or a float button on the desktop which
can close the virtual keyboard, then the virtual keyboard will be closed
and the input method mode should be set physical keyboard.
