* Choose by name component to embed into composite UI as a regular Swing {@linkplain #getPanel() JPanel} (e.g. as part of a dialog with other controls).
* Don't forget to register instance with owner {@link com.intellij.openapi.Disposable} with {@code Disposer.register(getDisposable(), myChoosePanel);}
* <p/>
* NOTIFICATIONS: This panel intentionally sends out element selection event only (either
* {@link Callback#elementChosen(Object)} or {@link MultiElementsCallback#elementChosen(Object)}).
* There's no sense in {@link Callback#onClose()} for the embeddable panel component. Besides, IDEA has no clear contract for onClose call, and it's
* not wise to rely on it (see https://youtrack.jetbrains.com/issue/IDEA-155319) anyway.
