fix(touch): raise the soft keyboard only for a tap on the visible focused EditLine

A chat line keeps the IME focus under a hidden board (interfacemodule
__HideWindows for an NPC dialog, the focus handed back by
UnlockWindow/DeactivateWindow), and IsPointInsideFocusedWindow only
checked its own show flag and rect, so taps on the NPC dialog or the
minimap buttons opened the keyboard. Require the whole parent chain to
render and the picked window to be the focused one or its child.
