onChartResize not firing

my use case is I want to determine the width of my resizeable chart so I can determine the appropriate level of rollup to display based on # of horizontal pixels and timerange. I was hoping the width was maybe passed to the onChartResize function as a param.

In any event, I can't get this function to fire. My code is

```
handleChartResize = (param) => {
console.log("resize!");
console.log(param);
};

```
...

```


{rows}


```

`handleTimeRangeChange` fires fine, but not the resize function when I change the window width (although the chart **is** responsive)
