Bug with tooltip for stacked horizontal bar chart

### Expected behavior

Proper tooltip shown on bar is hovered.

### Current behavior

Seems like areas for tooltips are shifted when bar chart is stacked.
Probably its because of `data.datasets[].stack` property. The bars are stacked, but tooltip areas act like there is no `stack` property.

### Reproducible sample

### Optional extra steps/info to reproduce

Just try to slide cursor over bars, and see which tooltip is shown
