I'm developing the ClickToFlash extension for Safari and the fact that some <object>s fire two beforeload events in very quick succession is something I noticed early on. It's relatively common, in fact. It's not random in that a given object seems to always fire it once or always twice, but I have no idea what characteristic of the object is determinant. Here's a real-life example of an embedded Windows Media video that always fires it twice:

Also, I noticed that in the attached example, as soon as you add some attributes to the object (eg. add type="blah"), resizing does not make it fire more events anymore. Doing that increases the count by 2 instead of 1. However, if you add something that actually launches a plugin, like type="application/x-shockwave-flash", the count only increases by 1.
