Improve panel scalability, fix panel bugs
- Defer the binding of AppComponent report handlers to prevent the user interface from freezing when there are a lot of components.
- AppComponentView .appComponent html element is not rendered when it's collapsed, this greatly decreases the rendering time when there are a lot of components.
- OpenAll/CloseAll operation doesn't slow down when clicked multiple times consecutively.
- Collection fetch works also if there aren't model indexes.
- Real time update of app components starts after fetch.
- App components views extend the parent events property.
