Some heat map box does not show tooltip on react-vis.

[supriya-somavnshi]

Hi ,

I am using react-vis (1.11.7) for heat map.
On mouse over on heat map boxes, sometime it shows tooltip and sometime does not show.
Example – ALYA ticker

Please give me suggestion where we are doing wrong in code.

Please find my attached code.
