I found one problem with this fix (or the new resize behavior).
Let's take a look at the notebook Zeppelin Tutorial. At first it is showing some graphs.
If we run a sql query (without the data), we will get an error which will burst out of the paragraph. (this PR fixes it).
If we then run the whole notebook, the query will run successfully and show a graph, however that graph height will be the one of the previous error.

Overall, the resizing aspect of the output is a bit tricky between content based height and manually set height.
TEXT type of output as well as HTML and ANGULAR are content based height.
Only TABLE type of output is responding to manually set height.

Guys, please let me know if this is ready to be merged - as we are about to restart the 0.5.6 release it can be a part of it, if ready.

@bzz I'm gonna try to find a solution that solves all cases this afternoon based on that fix.
If I don't come up with something, let's merge this one

I don't know how I got that case before, just tried again and got no problem.
LGTM
