Great! but you dont't need to add an extra signal to watch the mouseDoubleClick, you can simply add your code above, and it work

    def mouseDoubleClickEvent(self, ev):
        # extra 双击 shape 编辑其名称
        if ev.button() == QtCore.Qt.LeftButton and self.editing() and len(self.selectedShapes or []) == 1:
            STORE.edit_label()
            self.selectShapes([]) # prevent click but cancel, next time not trigger edit
            return
        # extra End

        if self.double_click != "close":
            return

        if (
                self.createMode == "polygon" and self.canCloseShape()
        ) or self.createMode in ["ai_polygon", "ai_mask"]:
            self.finalise()
