[IMP] web: Dialog: add option to stop click propagation

There are situations where we don't want clicks to be detected behind an opened
dialog: for example, when a dialog is opened by a dropdown, we may want to keep the
dropdown open while we interact with the dialog.

There is now an option (default: true) to stop clicks propagation when
they arrive at the dialog container.
