// but it's keyrelease+keypress in Qt. So here we do the inverse mapping as
// the one done in KHTMLView: generate two events for one DOM auto-repeat keypress.
// Similarly, DOM keypress events with non-autorepeat Qt event do nothing here,
// because the matching Qt keypress event was already sent from DOM keydown event.
// Reverse drawing as the one in KHTMLView:
// DOM: Down Press | Press | Up
// Qt: (nothing) Press | Release(autorepeat) + Press(autorepeat) | Release
//
// Qt::KeyPress is sent for DOM keypress and not DOM keydown to allow
// sites to block a key with onkeypress, #99749
