Due to the change, I can see here the cloned slides will no be rendered on SSR.

Follow up of #444
After more investigation into unrecoverable hydration issues, I finally found what was causing the cloned slides to not update on mounted
I has to do with cloneVNode which when cloning the node preserves the
elof the target vNode.. But that vNode being mounted already has aelmeaning vue doesn't try to add the vNode to the domI reverted most of #444 and instead just set el to null on the clone which fixes all of the issues
