[Pushed] 1.8.20 Editor Center issue

[Darkrad]

Reproduction steps:

1. In message editor, center your text.
   
2. Preview your post OR send your message.
   
3. Notice that your text isn't centered anymore.
   

If you write align=center yourself, it works. If you use button for it, it doesn't.

With button its working initially, but if you see source mode or preview the alignment bbcode is getting vanished. Yes.
Button usage in source mode is working fine, even while viewing preview ...
