The context menu event created when pressing the menu key does not contain the keyboard modifiers

The context menu event created on X11 systems when pressing the menu key does not contain the keyboard modifiers, the offending code is in qkeymapper_x11.cpp, in the QKeyMapper::sendKeyEvent() function and looks like

QContextMenuEvent e(QContextMenuEvent::Keyboard, pos, globalPos);

but should instead read

QContextMenuEvent e(QContextMenuEvent::Keyboard, pos, globalPos, modifiers);
