Maintain value after dismiss modal

[shifenis]

As the title described, the modal should not remove the value while closing the modal: from the UX point of view, the user expects the X button will not delete his previous selection, but just dismiss the modal. I know there is a backButton, but even in this case, a modal (so a page that came from bottom to top) without navigation should not have a back arrow, because it assumes there is a page before and not behind it.

In fact, in the code you can find:

	private _onClose(): void {
		const { onClosed, onSelected, requireSelection, selected } = this.props;
		const { modalVisible, selectedObject } = this.state;

		if (requireSelection && (selectedObject && ![selectedObject.Id]) && (selected && ![selected.Id])) return;

		if (!requireSelection) {
			onSelected({} as IModalListInDto);
		}

		this.setState({
			selectedObject: {} as IModalListInDto, // RESETTING 
			modalVisible: !modalVisible,
		});
		this.clearComponent();
		if (onClosed) {
			onClosed();
		}
	}

As you can see, the state will update with an empty object when the user closes the modal.
So, after that, the question is: is an architecture behavior to clear the selectedObject?

Otherwise, I can even make a PR to update this.

Hoping my point it's clear.
