console.log('detach') in NPM package

I have angular-tree-component which has these dependencies:

+-- angular-tree-component@6.0.0 | +-- mobx@3.4.0 | `-- mobx-angular@2.0.0

When I expand a node in my tree view, I see "detach" logs from the console.

Looking where it comes from, it points me to node_modules/mobx-angular/dist/directives/mobx-autorun.directive.js.

The code inside:

MobxAutorunDirective.prototype.autoDetect = function (view) {
        if (!this.mobxAutorun || !this.mobxAutorun.dontDetach) {
            console.log('detach');
            view.detach();
        }
        var autorunName = view._view.component
            ? view._view.component.constructor.name + ".detectChanges()" // angular 4+
            : view._view.parentView.context.constructor.name + ".detectChanges()"; // angular 2
        this.dispose = autorun(autorunName, function () { return view['detectChanges'](); });
    };

There's an extra block that logs and call to view.detach that isn't in the actual code on github

Not sure where it comes from. Maybe the repository wasn't clean when it got published to NPM?

Thanks!
