### Reproducible sample

### Optional extra steps/info to reproduce

Create a Polar area or Radar/spider chart and add it to the same page(single page).
You can verify the same font size and font family are applied to both chart.

I've checked this issue with the latest chart js library
Ref: https://www.jsdelivr.com/package/npm/chart.js?path=dist

Set below default options:
`Chart.defaults.font.family = ''`
`Chart.defaults.font.size = '18'`
