`no-unknown-property` doesn't prevent use of unknown properties?

See original GitHub issue

Today React gave me an “unknown prop” warning:

In this example, I gave my div element an abc attribute, which is obviously invalid HTML.

I was surprised that my linter didn’t pick up on this. Looking at the documentation, the name and description of the no-unknown-property rule lead me to believe that this should be caught, but that doesn’t appear to be the case.

So, I suppose this is a feature request: add a rule to catch invalid DOM properties.

Phew. This issue looked like “nice and small”, but well, was more detective work than I expected 😅

If anyone has more use cases than <div abc="foo" />, feel free to read through and comment on the PR #3377
