Change defaults after render leads to: TypeError: Cannot read properties of undefined (reading 'height') #12196
Description
Expected behavior
I would expect exception on changing defaults after render or correctly react on new values.
Current behavior
It may be minor but I spent one day debugging it. When you set Chart.defaults.font after render with responsive: true you can get NPE and puzzle over the reasons. It may happen when you do in the React app in different places.
