There is an internal test of the 'rangechange' event having an inProgress property, but the test was disabled in October 2021, with the comment (by me) that the test seems to not be coordinated with actual events. The 'rangechange' event is not documented, and I don't know exactly what its behavior should be, but you might try it. There is a chart event type of 'rangechange' and the ChartRangeFilter has an internal chart, so perhaps one would need to access the internal chart to get at its rangechange event, but there is no api for that at the moment.
Anyway, something broke along the way during the many refactorings over the last few years. It would help to figure out which older version of Google Charts still works correctly so we can narrow it down a bit. If you could test loading version 50, 49, etc, that would be great.
