Sometimes expanding a call stack will not show any decendants. Steps: 1) Load http://webkit.org/misc/drosera/ 2) Enable profiling in the Inspector. 3) Click "Nested functions" button. 4) View the profile. 5) Expand then colapse the "rot" call. 6) Sort by Calls. 7) Try to expand the same "rot" call. Results: Disclosure triangle expands but no decendancts show up. Expected: The decendancts should show up in the rows below. This might be a bug in DataGrid.js.
