Isotope synchronous growth item and repositioning items

[ghost]

I'm trying to adjust a plugin isotope for the needs of my project. I need to synchronously reposition the items inside the container by increasing its height. The height is increased by the plugin jQuery-Collapse (http://webcloud.se/jQuery-Collapse/) when clicking on items inside the container. Here the fiddle:

As seen in the example with increasing height elements located below - little jump up at recalculation position. It is necessary to avoid it.I would be grateful for any help!

Because the item size is determined by the size of the content, we can't use the technique covered in the docs. Sorry, but this behavior is the most suitable in this scenario.
