    imwayland: Connect OSK activating gesture to parent widget on editables
    
    The gesture as connected currently on the child GtkText is easily overridden
    by the parent editables (and gently done so in the attempt to consume all
    clicks).
    
    Connect this gesture to the parent editable widget in these cases, so the
    gesture can cohabit with the click-consuming one. It's not part of the same
    group, but it won't be abruptly cancelled.
    
    Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4795
