Well, that's incorrect, it's linked from https://w3c.github.io/sensors/#update-latest-reading.

I'm no sure what you mean.

Well, if this is really important to you, why don't you go-ahead and fix the HTML spec directly? That's a much better solution.

I agree this would be cleaner and match people's mental model better. But the current solution is as normatively correct as the desired one (which, as I said, can't be specified right now).

Get this fixed in the WHATWG HTML spec and I'll be super happy to fix it here.

In the meantime, I am not interested in replacing normatively correct text by a flaky solution.
