@elcollie,
You seem to be using undocumented methods and properties. addTheme is an internal property with certain functionality and might not apply font-size as defined across all the elements in the chart. We suggest you use chart.options to set the labelFontSize in this case since it will apply the font-size based on the defined value.
addTheme
chart.options
