Hello. How can I use MouseEvents for my / extension of existing components (For example, window, and specifically I need a double click on the header)? As far as I understand, I need the "_id" property (webix UI v.5.4.0 GPL> webix_debug.js l.6818) which is not available in production mode. Is it possible to make this property not "private"? Or maybe there is another way to solve the problem?
