Automatic update from web-platform-tests Use the block-in-inline layout result when considering breaks. The layout result for the line box that's wrapped around the block- in-inline isn't very useful when it comes to considering break points. In order to get access to any block break token inside, for instance, we need the layout result and fragment of the anonymous block, not the line box. We were making an incorrect decision to break before an element in MovePastBreakpoint() because of this bug. Since we failed to realize that the child had actually broken inside (since we didn't see the break tokens that were actually there), we'd instead check if the child was taller than the remaining space - which it was. So we ended up breaking before at a last-resort break point, instead of using the breakpoint that we had already found inside. This is a rather bizarre situation, and in this case it's caused by underlying bugs. But at least we will no longer freeze / crash, with this CL. We should also be able to remove code added by CL:4181113 from NGInlineLayoutAlgorithm::PlaceBlockInInline() (setting the break appeal there manually should no longer be necessary), now that we use the "right" layout result for fragmentation considerations. But since this CL is likely to be merged to older versions, let's keep it as safe and merge-friendly as possible. NGBoxFragmentBuilder::AddResult() should also call the new function LayoutResultForPropagation() instead of doing the work on its own, but for the same reason as above, leave it alone for now.
