+## Limitations
+
+Care should be taken when destroying and then re-attaching custom elements created with `@angular/elements` due to issues with the [disconnect()](https://github.com/angular/angular/issues/38778) callback. Cases where you may run into this issue are:
+
+- Rendering a component in an `ng-if` or `ng-repeat` in `AngularJs`
+- Manually detaching and re-attaching an element to the DOM
