    @zsxwing Did you profile after patching? I spent some times to profile 
before-patching and after-patching 2 times for each, with 10000 tasks. I 
couldn't recognized significant performance up of rendering. 
    
    To make matters worse, the timeline is not available until the entire page 
has been done to render.
