This is needed for patch 4. This is based both on the wording in the spec and the discussion in https://github.com/w3c/csswg-drafts/issues/2987, and also doesn't support them for nsMathMLContainerFrame, which is similar to inlines and ruby. Differential Revision: https://phabricator.services.mozilla.com/D2815 --HG-- extra : rebase_source : b7e23fb248fa34957ca2d539134e872f5a03f5a8
