I think it works only on type text? I tab and enter out of habit, but to be fair, enter without tab works here. But then again (and many will feel I'm being nit-picky but you're just hearing from someone who had to conquer a lot of a11y audits at job, so just let me have different priorities), the whole node gets replaced without any announcement, Voiceover being left clueless about what happened. NVDA would probably be the same, but I'm on vacation and cannot test on windows right now.

This is a simple form, not a complicated thing, and it's the website of a company I love, so I'm paying extra attention perhaps.
