invalidateChartStyles

Tells every chart on the page that the host changed its styles in a way the charts cannot observe: a CSSOM edit (a rule inserted or deleted, sheet.disabled, <style>.disabled), an adopted stylesheet, a stylesheet outside <head>, or a media condition other than the colour scheme and forced colours that starts or stops matching. Charts re-read their tokens and fonts in their own scope. It carries no value and sets no theme; a change of a class, an inline custom property, or a head stylesheet element and its activation attributes needs no call.
