-webkit-margin-collpase is a non-standard extension added in https://trac.webkit.org/changeset/7362/webkit. I wonder if we can remove it.

Just for future reference, this is the comment from ikilpatrick@ on the duplicated bug: Blink is going to attempt to remove this in the M81 release, see: https://bugs.chromium.org/p/chromium/issues/detail?id=1030765 https://groups.google.com/a/chromium.org/forum/#!msg/blink-dev/ewWQH9vEqtI/L2r2WFhPBAAJ
