For any regular use of views, this should not happen. I'd be interested in seeing a testcase, I'd be willing to bet it's the use of height: contentHeight causing delegates to be created for everything (which we really need to move away from, anyhow).

From that perspective (though by all means let's look at a testcase) I'd like to avoid this part of the change, because while it may make our (bad) case worse, it pessimises well-written view use.
