This is correct in node env, not in jsdom. Unsure if we care about that differentiation?

The differences are small, but I'm not sure it should affect this fix

Node:
Chrome:
The output is pretty different

@SimenB If I understand correctly, jsdom forwards its output to the Node.js console by default.
I'm not sure that we should print different messages (AssertionError [ERR_ASSERTION]/Assertion failed) depends on the environment.
What do you suggest?

https://nodejs.org/api/console.html#console_console_assert_value_message_args
Note: The console.assert() method is implemented differently in Node.js than the console.assert() method available in browsers.
Specifically, in browsers, calling console.assert() with a falsy assertion will cause the message to be printed to the console without interrupting execution of subsequent code. In Node.js, however, a falsy assertion will cause an AssertionError to be thrown.
Should we respect that? We'd have to pass environment, or detect jsdom/node otherwise. Personally I'd like console.assert errors to always be caught, like in browsers.

Yes, I agree with you about it, because otherwise, the assertion error would fail the test.

let's just use assert(...args) since extra arguments are irrelevant to it. Same for buffered console.

Summary
This is a fix for #5574
There was a mistake in #5514, where the
console.assertbehaviour was accidenitly implemented wrong.Here there is a fix for the tests and the behaviour to use
assertmodule and log when there is an assertion error.
