I am working on upgrading to 2014.1.403. I use setSize() a lot, and I think there is a problem with it in the new version. After calling setSize, the editor resizes properly, but one of the tables within the editor layout (class reLayoutWrapper) is still set to its default height of 400px. This only occurs if the new height is less than 400px - if it is more, the reLayoutWrapper table is resized to match.
I resolved the problem for now with: $("table.reLayoutWrapper").height(myNewHeight);
