Microsoft did a lot of weird things like that - also with Outlook, which used to use Trident to render emails, when IE was finally getting a bit better the Office team decided to switch Outlook to use the far, far worse Word HTML rendering engine instead... Even thinking of that makes me very happy I haven't had to worry about formatting email newsletters for more than 10 years now, brings back bad memories...
