Sync web-platform-tests PR 10304 into mozilla-central (this bug is closed when the sync is complete). PR: https://github.com/w3c/web-platform-tests/pull/10304 Details from upstream follow. Morten Stenshorne <mstensho@chromium.org> wrote: > Out-of-flow descendants may still be part of the flow thread. > > When changing a layout object from in-flow to out-of-flow positioned, we > used to just remove it from the flow thread, risking that there'd no > longer be a column set to associate it with.
