dynamic-injection-growth

A session in which dynamic() has injected so many classes the CSSOM keeps growing.

• It is printed to the console. A production browser bundle leaves it out.

Message

A name in angle brackets is a value the message fills in.

[csszyx] dynamic-injection-growth: `dynamic()` has injected <count> or more unique classes this session, and injected CSS rules are never removed, so the CSSOM keeps growing and style recalculation slows.
  help: drive continuously changing values, such as a width that changes every animation frame, through a CSS variable instead.
