Error in summaries when expanding / collapsing resources

Hello, we get an console error for a specific scenario when using the summaries feature. Can this be fixed in the scheduler? Or is there a workaround to avoid this error?

Scenario: having summaries enabled when expanding the scheduler splitter, then expanding some of the records and then collapsing back the splitter, a console error appears and the summaries are not shown anymore.

To reproduce the problem, use Bryntum scheduler example for tasks https://bryntum.com/products/scheduler/examples/tasks/.

To this, I add summaries from example: https://bryntum.com/products/scheduler/examples/multisummary/.

Steps:
Collapse all employees
Expand splitter
Expand one employee
Collapse splitter

=> Error: Uncaught (in promise) TypeError: Cannot read properties of null (reading 'classList');

Thanks
