Error with private method access in mockAnimationApi()

[madeleineostoja]

When using mockAnimationApi() I get the following error:

TypeError: Cannot access private method

Digging through the stack a bit it seems to be happening in getComputedTiming which calls #getNormalizedDuration

jsdom-testing-mocks/src/mocks/web-animations-api/AnimationEffect.ts

Line 32 in 4ae6e7b

getComputedTiming(): ComputedEffectTiming {

jsdom-testing-mocks/src/mocks/web-animations-api/AnimationEffect.ts

Line 34 in 4ae6e7b

const duration = this.#getNormalizedDuration();

)

Unsure why that's erroring in the transpiled code though 🤷🏻‍♀️
