That's actually a common example of when those little differences matter: when the client-side markdown implementation (preview button) doesn't line up with the server-side implementation (render). There's nothing to lose by having a standard. Most markdown libraries I've used let you configure between various flavors of markdown. I'd love to enable "Standard Markdown mode" on two different implementations that need to produce the same output and be done with it.
