In order to support a recent use case I had to create my own wrapper around EuiModal. The wrapper is the same as EuiConfirmModal except that it allows passing in isLoading and ownFocus props.

• isLoading is used to disable the confirm button and show loading spinner for async operations. An example of this are the countless confirm to delete modals in stack management.
• ownFocus renders the modal inside an overlay mask similar to how EuiFlyout supports this.
• When the overlay is clicked the onCancel callback is triggered to be able to easily dismiss the modal (This does not happen when isLoading prop is true to stop accidental dismissal)
