hoverBackgroundColor affects tooltip index color

Version : v2.8.0 Configuration :

chartDataSets.push({
                    label: category,
                    barPercentage: 0.5,
                    barThickness: 6,
                    maxBarThickness: 8,
                    minBarLength: 2,
                    backgroundColor: this.getThemeColor(index),
                    data: categoryData,
                    hoverBorderColor : '#D7DAE9',
                    hoverBorderWidth : 2,
                    hoverBackgroundColor  : '#D7DAE9'
 }); 

Expected :

Actual : The tool-tip index colors are overridden by the hoverBackgroundColor

Workaround :

1. Remove hoverBackgroundColor
2. Set hoverBorderColor
3. Set hoverBorderWidth to a higher value overlapping the whole bar area

As @LeeLenaleee mentioned, this was likely fixed when @kurkle rewrote the animation system. Our initial goal was to improve performance, but we did catch some bugs during the project. We’ve got better test coverage on that now, so this should be stable in v3.

Don’t know but if it is a duplciate but it can also be fixed because they noticed the issue themselfs and for v3 they rewrote a large part of the lib what could have fixed it
