ResultSet.chartPivot keys issue

[keydunov]

It looks like ResultSet.chartPivot uses weird combination of keys and titles as keys Object returning by chartPivot.

// What is returned by resultSet.seriesNames()
[
  {title: "Reports, Events Any Event - Total", key: "Reports:Events.anyEvent"},
  {title: "Dashboard, Events Any Event - Total", key: "Dashboard:Events.anyEvent"},
  {title: "∅, Events Any Event - Total", key: "∅:Events.anyEvent"}
]

// What is returned by resultSet.chartPivot()
[
{category: "2019-02-05T00:00:00.000", x: "2019-02-05T00:00:00.000", ∅, Events.anyEvent: 0, Reports, Events.anyEvent: 0, Dashboard, Events.anyEvent: 0, …},
{category: "2019-02-06T00:00:00.000", x: "2019-02-06T00:00:00.000", ∅, Events.anyEvent: 0, Reports, Events.anyEvent: 0, Dashboard, Events.anyEvent: 0, …},
{category: "2019-02-07T00:00:00.000", x: "2019-02-07T00:00:00.000", ∅, Events.anyEvent: 0, Reports, Events.anyEvent: 0, Dashboard, Events.anyEvent: 0, …},
{category: "2019-02-08T00:00:00.000", x: "2019-02-08T00:00:00.000", ∅, Events.anyEvent: 0, Reports, Events.anyEvent: 0, Dashboard, Events.anyEvent: 0, …}
...

The key in the chartPivot returning object is Reports, Events.anyEvent which is neither key nor title from seriesNames. I'd suggest using keys.
