           Summary: Enabling spellchecking slows down selection even when
                    nothing is editable
           Product: WebKit
           Version: 522+ (nightly)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Forms
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: marv.decker at gmail.com


Frame::respondToChangedSelection asks if the current webview has spellchecking
enabled and then triggers a lot of extra logic involving computing ranges,
adding and removing markers, checking words, etc. This happens even when the
selection isn't over a form control that can have spellchecking.

For example, go to a relatively complex page with few form controls like Google
News. Select some text in one of the blurbs and scrub the mouse around. If
isContinuousSpellCheckingEnabled returns true, the selection is dramatically
slower than if it returns false.
