Description

Reading through the documentation, I was tripped up by the usage of generally here:

Calling this.setState() generally doesn’t trigger componentWillReceiveProps().

I was trying to imagine a way for a single component to trigger componentWillReceiveProps() on itself as a result of a setState() call, but I think that should not be the case, should it? Does it refer to the possiblity of setState() triggering a re-render in the parent component?

Research direction

Locate the documentation passage containing the quoted sentence and review the surrounding explanation of setState() and componentWillReceiveProps(). Confirm the intended lifecycle behavior, then clarify the wording so readers understand when componentWillReceiveProps() is or is not triggered. Done means the documentation no longer leaves the stated ambiguity.
