The height and width styles are handled by #4345.
Sortable does preserve the
property originally declared in CSS. What it does not do is handle two lists that have different
property values. But if you have connected lists you're almost going to want them to have the same display property value. Can anybody think of any use cases of different displays (block / inline-block / inline)?
I'm leaning towards the being something that we don't support. This would be tricky to implement, I can't think of any real use cases where this would be useful, and it's easy to workaround. If you really need it !important can be used (http://jsfiddle.net/tj_vantoll/Caw5Q/) or you can restore the style manually in a stop event.
