Missing coverage encountered while implementing <https://github.com/tc39/ecma262/pull/3307> in SpiderMonkey. Ensure environment lookups are performed in the correct order: - keyed-destructuring-property-reference-target-evaluation-order-with-bindings.js Ensure `delete super[elem]` steps are correctly performed: - delete/super-property-topropertykey.js - delete/super-property-uninitialized-this.js Ensure ToPropertyKey for computed property names in object literals correctly performed: - object/computed-property-name-topropertykey-before-value-evaluation.js Ensure `GetSuperBase` is executed before `ToPropertKey`: - super/prop-expr-getsuperbase-before-topropertykey-* Ensure `GetThisBinding` is executed first: - super/prop-expr-uninitialized-this-*
