Describe the problem
You have two charts on an Excel sheet and you add onActivated and onDeactivated methods to either the individual Charts or the ChartCollection, as in the linked example. If you click one chart then onActivated fires. If you then shift-click the second chart, onDeactivated fires on the first chart, even though it is still active.

I recently realised the web version of Excel (which I rarely use) does not allow multiple selection of charts or shapes, which I guess is the source of this problem. In desktop Excel though the current behaviour is not right. If it can't be fixed, a note in the documentation could be added.

The overall context is I'm trying to create an add-in to apply bulk formatting to charts, and was trying to use events to write my own version of getActiveCharts in the absence of a built-in method. There is only the singular getActiveChart.

Thanks for reporting this @NickRedwood. I'm going to transfer it to the office-js repo and get a member of the Excel feature crew to take a look.

I have found that the Excel.Shape onActivated and onDeactivated methods work correctly for multiple selection, and I think I may be able to use those for Chart, though yet to flesh that out. Unfortunately there is no onActivated and onDeactivated method on ShapeCollection. No getActiveShapes either, or onAdded, onRemoved.
