Pie chart overrides not working as expected

[omkensey]

I'm initializing the plugin config as follows:

			Reveal.initialize({
                                //[...]
				plugins: [ RevealChart ],
				chart: {
					overrides: {
						pie: {
							plugins: {
								legend: {
									maxHeight: 150,
									labels: {
										font: {
											size: 48
										}
									}
								}
							}
						}
					}
				}
			});

However, when I create a pie chart, the legend labels are still small unless I explicitly set options.plugin.legend.labels.font.size (see https://jsfiddle.net/unjapkx6/1/ for example).

What's the correct way to set the overrides in the chart config?
