           Summary: Document::recalcStyle(Force) called for every
                    updateStyleIgnorePendingStylesheets while waiting for
                    stylesheets
           Product: WebKit
           Version: 522+ (nightly)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P3
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mitz at webkit.org


If stylesheets have not yet loaded, updateStyleIgnorePendingStylesheets() will
call updateStyleSelector() which calls recalcStyle(Force).

This is *not* a regression from the m_didCalculateStyleSelector patch (which
fixed a Yahoo! Mail crash), but still would be nice to fix at some point.
Basically you need updateStyleSelector() to only set a flag and postpone the
update until later when you need it.
