Gtk4 set a GtkText insensitive on mouse leave event yields Gtk warning

I am using a non-editable, non-senstiive GtkText inside a ListBoxRow and set the GtkText editable and sensitive on row activation. My goal is to display the GtkText the same way as if it was a GtkLabel, but also allow edition only on row activation, and disallow it on mouse leave event.

On mouse leave event on the GtkText (captured with a GtkEventControllerMotion) I reset the GtkText to non-sensitive and non-editable. I understand this breaks the flow of event propagation, but I don’t know how to work around that. On mouse leave event, i get such a warning:

GtkText - did not receive a focus-out event.
If you handle this event, you must return
GDK_EVENT_PROPAGATE so the default handler
gets the event as well

The relevant “on mouse leave” Vala code is as follow:

        /* in row constructor */
        label = new Text ();
        label.editable = false;
        label.sensitive = false;
        var mouse_ev = new Gtk.EventControllerMotion ();
        mouse_ev.leave.connect_after (() => { label.editable = label.sensitive = false; text_edited (label.text); });

        // useless alternate code
        // mouse_ev.leave.connect_after (() => { GLib.Idle.add (() => { label.editable = label.sensitive = false; return false; }); text_edited (label.text); });

        label.add_controller (mouse_ev);
        ...

I’m stuck on how to get rid of the warning message. I’m probably doing this wrong, even if from the UX point of view, the code works as expected.

I finally found a solution.
instead of setting the sensitive flag to false, i modify the wisget’s state_flags as is:

    public void set_editable (bool enable) {
        label.focusable = label.editable = enable;

        if (enable) {
            label.sensitive = true;
            label.grab_focus ();
        } else {
            /* avoid "focus-out" warning */
            label.set_state_flags (Gtk.StateFlags.INSENSITIVE, true);
        }
