            Bug ID: 185411
           Summary: [Simple line layout] Cache run and line resolvers.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

Whenever a (run/line)resolver is constructed (for painting/hit testing) we iterate through and collect all the flow's content in FlowContents's c'tor.
In case of long text content with large amount of elements (foobar1<br>foobar2<br>.....foobar9999<br>) this repeated work could hang the WebProcess.
