gantt: setState was asked to show a view but no container is known yet; call mount()/mountSplit() at least once first.

Since

1.50.0

What happened

The state being restored says a view was mounted, and this controller has never been given an element to draw into, so there is nowhere to put it. The rest of the state is not applied either - the call returns straight away - and nothing is rendered.

The fix

Mount the plan once before restoring state; the controller then remembers the container and setState can re-show the right view.

The smallest fix

gantt.mountSplit(el);
gantt.setState(saved);
