The base is an embellished operator with the largeop property. 2. The base is an embellished operator with the stretchy property and stretch axis inline. Currently, the underover algorithm only checks if the base is an element. This CL modifies to instead check whether it is an embellished operators and if that's the case retrieve these properties from the core operator. New WPT tests are added to cover the changes from this CL: - underover-parameters-and-embellished-operator-1.html is a copy of underover-parameters-and-operator-1.html with embellished with an . It checks (1) above. - underover-parameters-and-embellished-operator-2.html is a copy of underover-parameters-and-operator-2.html with embellished with an . It checks (2) above.
