Date format error in tooltip when splitting a chart with date histogram

Hello,

When splitting chart with Date Histogram, the date is properly formatted in the axis label but it is in timestamp format inside the tooltip.


I'm using Kibana 7.5.0 but I see the issue in Kibana demo which is currently 7.4.2

There is a possibly related issue fixing the axis label

Is there a workaround for this? I would like to modify whats shown in the tooltip.

Thanks
