Bug report

Plotting a simple bar chart of time series data using a VictoryStack fails to render correctly. Only a subset of the bars are rendered.

// this chart doesn't render all the bars

<VictoryChart scale={{ x: "time" }}>
    <VictoryStack colorScale={"qualitative"}>
        <VictoryBar barWidth={5} data={DSTChangeDay1} />
    </VictoryStack>
</VictoryChart>

Plotting the same data without wrapping the Bar in a Stack works correctly.

// this works fine

      <VictoryChart scale={{ x: "time" }}>
        <VictoryBar barWidth={3} data={DSTChangeDay1} />
      </VictoryChart>

### Steps to reproduce

```markdown
1. Go to [code sandbox](https://codesandbox.io/p/sandbox/multiple-axes-with-victorygroup-forked-m6dm4h?workspaceId=90ff9bfc-5f7c-41ee-be73-afe0ddcdced4)
2. Look at the first chart rendering correctly
3. Look at the second chart rendering a subset of the bars

Expected behavior

Stack should render all the bars. If we use a time series that does not include a Daylight Savings change, then it all works correctly.

Actual behavior

Not all bars are rendered for a Stack chart when using a time series where daylight savings time change happens

Changing the ordering fixes this for some reason!

Chart works with the point

    y: 0.118,
  }

Sorting the chart data fixes this - there is probably a bug here, but this is a reasonable workaround.

function sortChartItems(a, b) {
    if (a.x < b.x) {
        return -1;
    } else if (a.x > b.x) {
        return 1;
    }
    // a must be equal to b
    return 0;
}
