Change the logic that moves the main summary to the front from operating on generated frames in DetailsFrame::SetInitialChildList() to operating on frame construction item list in AddFrameConstructionItemsInternal() so that it will be correct when cooperating with ::first-line. The root cause of the bug reported is because when specifying ::first-line on details element, the first frame of summary element, which is generated due to ib-split, will be wrapped in nsFirstLineFrame. The original code fails to find the summary frame in the wrapper frame and triggers assertion because of the second ib-split summary frame. To fix that, we need to descend into the child list of wrapper frames when checking the main summary. Add original test case as a crashtest as well as reftests to clearly reproduce the issue. Note that in the reftest, the blue color in ::first-line is applied incorrectly to the second line in the summary due to bug 520605. MozReview-Commit-ID: Bv4Vcvxp6pY |
