If Chrome is made by Google, why does it suck at publishing in Blogger?

Just a simple question - Blogger is owned by Google, so one would think that their own browser Chrome would do the best possible job when working in Blogger.

Right?
Wrong - at least in my experience.

Trouble is, when I post to Blogger in Chrome, my published post never stays true to the line formatting / spacing that I used when typing the post.
For example - single line spacing in Chrome get published to Blogger as double line spacing, yet in IE8 it does not.

Blogger and Chrome - please play nice!

Techies at Google - please help?
