If it fails to render a particular page as intended.

"As intended" is not necessarily a deterministic metric, particularly in the absence of specific font selections, weights, etc in markup. We can infer what the page creator intends when such things are present, but in the absence of such specifications a client is free to render elements however it wishes.

Or, the TL;DR version: Precisely how should an entity enclosed in H2 tags be rendered?

Precisely - and exactly the reason why I've switched back to Internet Explorer. I mean, if you can't trust Microsoft, who can you trust?

That's absurd and you know it.

I'm criticising the assertion that open-source is some kind of totem against software defects.

Nice of you to think that any criticism of "Open Source" really means "Use Closed Source" (It doesn't.)!

It's April Fool's Day, Syn. Of course it's absurd. I happen to agree with you.
