Steps to Reproduce

1. visit my codepen url above
2. click "Animals" bar (universalTransition animation works)
3. click "Back" (not works)
4. comment line 12 dataGroupId: "", and repeat 2 and 3 they both will work

Current Behavior

Hi, Echarts core team!

I have read the related source code so I know where the problem occurs.

When processing old data items, after executing this line, dataGroupId is wrongly assigned to a value that is belong to new data items, which is due to the factor of having notMerge default set to false when .setOption(newOption).

This bug will not be exposed when data item's groupId is specified.

Expected Behavior

Old data items should be given correct dataGroupId when item.groupId is not specified.

Environment

- OS: macOS Monterey
- Browser: Chrome 103
- Framework: None

Any additional comments?
