Why change onload triger time?

[James]

in 1.8.5 if I use winodw to load a page with script , page's script will triger before onload function, but in 1.8.8 it runs after onload function , I used to reset window height by read window object’s scrollHeight in onload function，and now it seems impossible，becase in the page，there are some easyui items，if onload run first, those items have not parseed yet, the scrollHeight will be smaller then it should be.
