Our teams have noticed an issue since we upgraded to Splunk 9.0.3 (from 8.1.x) with the chart legend interactions. When the legend is a long list of series, attempting to scroll the legend list by clicking on the "scroll button" is instead mistakenly interpreted as a click on one of the legend's series, causing a drilldown search. This is seen, at least, in the Search Assistant.
Has anyone else seen this? Is it a known (to Splunk) problem? Any idea which versions/situations do/don't exhibit the bug?
