Cannot open Virtual Keyboard using cursor mode

My app is developed using a canvas for UI display rather than HTML DOM elements. When displaying a form for the user to complete, we create a new input tag & apply focus to it in order to call up the LG Virtual Keyboard.

This process works well when the remote is using directional navigation (arrow keys) but is not responding properly when the remote is in cursor (mouse) mode.

When selecting the desired text field on screen using the cursor, our code is activated & creates & focuses the input but the system always fires the keyboardStateChange event with visibility of false

[WAM] fires keyboardStateChange event : false

Please refer to Remote Control sample app. When the cursor is activated and is moving onto a UI element, the focus by the navigation keys must be switched to the focus by the cursor on the current position. Thank you.
