### Steps to Reproduce
1. select points A,C,D
2. double click point _dblclick_ to switch data
3. selection changes to A,B,F
### Current Behavior
Selection changes from A,C,D to A,B,F
### Expected Behavior
the two data sets have common points A,B,C and unique points D,E and F.
When switching data I would expect the **selection of common points** to remain the same.
### Environment
```markdown
- OS: Win 10
- Browser: Chrome
- Framework: JS
```
### Any additional comments?
It is not clear what are the rules for persistent selection.

It seems selection goes by **data indexes**. When data is in the same order, like so
```
data1 = [
[4.05, 3, 'A'],
[5.02, 5, 'B'],
[6.03, 7.24, 'C'],
[7.08, 6, 'dblclick'],
[11.0, 7, 'D'],
[12.0, 8.84, 'E'],
]
data2 = [
[4.05, 3, 'A'],
[5.02, 5, 'B'],
[6.03, 7.24, 'C'],
[7.08, 6, 'dblclick'],
[10.0, 8, 'F'],
];
```
then selection is more consistent - A,C remains A,C, only D changes to F.
I guess it's up to the developer to handle select/unselect thru actions
``` this.dispatchAction({type: 'unselect', seriesIndex: 0, dataIndex: [0,2,4] }); ```
