            Bug ID: 195317
           Summary: Web Inspector: recordsInTimeRange sometimes does not
                    get the expected record when includeRecordBeforeStart
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org

recordsInTimeRange sometimes does not get the expected record when includeRecordBeforeStart

For example, when the before record is a composite of a bunch of paints:

    - Composite:
        - Paint: ...
        - Paint: ...
        - Paint: ...
        - Paint: ...

Currently we get the inner Paint, but that isn't as useful as the Composite, which may be much longer in duration.

Steps to Reproduce:
1. Record CPU Timeline on maps.google.com zooming in/out
2. Select part of the large composite and view the CPU Timeline graph
  => Main Thread indicator doesn't see paints when it should
