If we make "preserves the context of the first call" testcase just slightly more complex, we clearly see it doesn't actually preserve the context of the 1st call as promised.
What it does is preserving the context of the 1st call after the last animation frame. When animation frames happen and how often is the last thing a developer wants to care about, so current behavior is close to unpredictable and thus unreliable.
I personally see 2 solutions to this problem:
lodash.throttle
). This is the smartest choice.
