Description
resolve #2184
According to the MDN documentation on the IntersectionObserver API, the default value of
threshold
should be 0. In #115, I did not find any discussion regardingthreshold
defaulting to 0.1. Should we maintain consistency with the IntersectionObserver API's default value? However, this would be a breaking change.https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API#threshold
