Describe the bug
Brushing action over the Y-axis labels triggers highlightes cells to the right and invoke onBrushEnd event.

Expected behaviour
Cells should not be highlighted because the cursor never appears on top. onBrushEnd event probably still can be triggered but it shouldn't contain any values from the X-axis labels.
