Cant align plugins.legent.labels correctly

[batata004]

Please take a look at this graph:

Look at the legend (printscreen below with zoom so you can see better) and see that its text is not vertically aligned with the box.

You can see in the code that I set both boxHeight and fontSize to 12 (I copied to you below) and despite that, the rectangle box is not well aligned with the text. I think you should vertical-align:middle both the box and the text so they get well aligned.

legend:{
	display:true,
	position:"top",
	align:"center",
	labels:{
		boxWidth:12,
		boxHeight:12,
		useBorderRadius:true,
		borderRadius:1,
		font:{
			size:12,
		}
	}
}
