           Summary: Javascript console should not attempt to scroll to end
                    of console if console is not visible
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2

* SUMMARY
Whenever a message is sent to the console the web inspector attempts to scroll
the appropriate portion of the console to be visible.  Unfortunately if the
console is not visible, this is very heavy wait operation as it requires
building the rendertree, calculating where it should scroll to, then throwing
the rendertree away.

* STEPS TO REPRODUCE
1. use javascript along the lines of javascript:while(1) console.log("foo")

* RESULTS
Shark shows 94% of time being spent in style recalc.
