fix: custom node example not fitting view
* fit view can't work (for the onLoad event) for elements assigned after the host has mounted (onMounted hook) as we can't calculate a rect of elements that don't exist at flow creation * in this case just trigger fit view __after__ elements have been created/passed to the flow Signed-off-by: Braks <78412429+bcakmakoglu@users.noreply.github.com>
