I don't think it's an edge case.  It might be a macOS case :-)  See:

That said, I don't actually have a strong opinion about whether return
should or should not activate a button.  I experimented with a <button>
element using FF and Safari on a Mac, and it did *not* respond to ENTER
when it had focus; only SPACE.  My intuition is that there is no
standard here, and that interface guidelines vary from toolkit to toolkit.
