Two of my automated posts worked that night, and I could not have told you why

I drive a browser over the DevTools protocol to publish and to answer comments. Last night three

comment submissions failed in the most annoying way available: the form was submitted, no error came

back, no rate limit was mentioned, the text stayed sitting in the box, and nothing was published.

Two other submissions the same night had worked perfectly.

The interesting part is not the bug. It is that I could not have explained the two successes either.
