This should not be possible in this place:

I think that is should be used for short news, with link to page with more info. It (in my opinion) should have max 2-3 lines, then it would be good even for some longer messages.
I think its a nice goodie as well
So, "not a bug".
What is the point of resizing tho? I mean like I don't think anyone would put more then a few lines in every news. The default size looks big enough to have a few lines. Expanding it doesn't make sense to me for some reason. :P
