Symbian: Copy and Cut actions do not appear in fullscreen VKB menu when a QML TextEdit element is focused

Copy and Cut actions do not appear in fullscreen VKB menu when a QML TextEdit or TextInput element is focused and has selected text. This happens because input method queries for cursor and anchor position in QCoeFepInputContext::CcpuCanCut() return zero in this case. It is probably related to focus changes when the options menu pops up.
