• [core] Cascade page size specified in @page rules to page masters defined by @-epubx-page-master rules
  • When @page rules and @-epubx-page-master rules are both specified, the page size specified by 'size' property in @page rules is applied to the selected page master. This behavior is not defined in the related specs.

Fixed
