Sync web-platform-tests PR 11688 into mozilla-central (this bug is closed when the sync is complete). PR: https://github.com/web-platform-tests/wpt/pull/11688 Details from upstream follow. Koji Ishii <kojii@chromium.org> wrote: > [LayoutNG] Allow epsilon when fitting into a line > > When NGLineBreaker tries to fit items into a line, rounding > errors are hard to avoid.
