            Bug ID: 234614
           Summary: Web Inspector: Sources: expanding a grouping of
                    blackboxed call frames should be persistent
           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
          Reporter: drousso at apple.com

# STEPS TO REPRODUCE
1. inspect <http://bogojoker.com/shell/>
2. create a "click" global Event Breakpoint
3. blackbox the <http://bogojoker.com/shell/js/jquery.js> script
4. click on the down arrow in the page
-> should pause on <http://bogojoker.com/shell/js/easySlider.min.js:64> with two blackboxed call frames
5. click on the "Blackboxed - 2 call frames" to expand
-> should see two call frames in jquery.js
6. Step into

## EXPECTED
the two jquery call frames remain as they are (i.e. are not re-collapsed)

## ACTUAL
the two jquery call frames are re-collapsed


# DISCUSSION

If the developer has explicitly decided to show blackboxed call frames, we should respect that decision.  Requiring them to re-expand after _every_ debugger action is very hostile.  I think so long as the blackboxed call frames remain the same we should persist the expansion.  Only if the location of those blackboxed frames changes should we re-collapse.
