This bug is to adapt WebKit to the following resolutions by the CSSWG: * Percentage row tracks: https://github.com/w3c/csswg-drafts/issues/1921 * Percentage row gutters: https://github.com/w3c/csswg-drafts/issues/509 The change has been already done in Blink (https://chromium.googlesource.com/chromium/src/+/47bfc59ccdda82e2b28817a653c792d7a606ee8e) so it'd be nice to follow it in WebKit too. Change for percentage row gutters has been also done in Firefox already.
