DataGrid - `Cannot read properties of undefined (reading 'done')` error occurs when column fixing and state storing are used

StateStoring bug with fixed column

created 4 days ago (modified 4 days ago)

Hi,

In version 24.2.6 there is a bug with StateStoring enabled and fixed column.
snippet

When both options are used DataGrid is not rendered properly and throws error Cannot read properties of undefined (reading 'done').
There is no such error in version 24.2.5

P.S.: Exception in the snippet is not reflected on first run (even on preview refresh).
Probably because of state not saved to storage yet.
To get the result try to make some operations (i.e. sort some column) and then refresh preview.
