Grid - preformatted text in column

Hello Everyone! :)

I encountered strange behaviour with Grid component. I wanted to display preformatted text in my Grid. I made BeanItemContainer holding my beans. In "Bean" class I made getter - getContent in which I returns Label with preformatted ContentMode:

Label area = new Label();
area.setValue(text);
area.setContentMode(ContentMode.PREFORMATTED);
area.setSizeFull();
return area;

Unfortunately in my Grid this data is not correctly rendered. I tried HtmlRenderer and in getConten I return String

<pre>....here goes content...</pre>

With this solution result is very suprising - please see attachment grid.png

On the other hand in Table Component there were no problems with rendering Label component - table.png.
Could anyone now how to present preformatted text in Grid? :)

Thanks! :)
