Id collision after `clearGroups` and `loadData` again

Hi I'm trying to use the tree-grouping feature, and would like to sometimes turn-off grouping and reload the resourceStore with new data... I have reloaded the resourceStore with the same procedure in the past with great success, but since adding the grouping feature have encountered an error, here is a way to reproduce it:

https://www.bryntum.com/products/scheduler/examples/tree-grouping/

in the console do the following steps to temporarily stop grouping and reload with new data ( NOTE: in our data we have pre-defined IDs and cannot assign new ones, we must be able to clear and reload on demand when the data changes... ):

#1 - pretend to have new data by saving a copy of the old data:
newData = scheduler.resourceStore.data.slice()

#2 - clear the groups (NOTE: not strictly necessary, will error without this step):
scheduler.clearGroups()

#3 - clear the data:
scheduler.resourceStore.removeAll()

#4 - add new data:
scheduler.resourceStore.loadDataAsync(newData)
