Errors when opening gantt with infinite scroll and collapsed graph

ghulamghousdev commented 1 month ago

Hi, while testing the latest Gantt version (v6.0.4), I discovered that when the Gantt starts with the graph collapsed and with the infinite scroll feature enabled, it throws an error in the console:

[b]Steps to reproduce it[/b]:

open the infinite scroll example: [url]https://bryntum.com/products/gantt/examples/infinite-scroll/[/url]
open the code editor
add [b]StateProvider[/b] to the imports and this two lines of code inside the gantt configuration:
```
stateId: 'pippo',
stateProvider: new StateProvider({ storage: 'local' })
```
collapse the graph part
let the system refresh (i did it by adding a new line to the code on the right)
the error is thrown in the console
