…der r=jonco This patch inverts the order in which we reject promises in AsyncModuleExecutionRejected to match AsyncModuleExecutionFulfilled: first the promise corresponding to the leaf module (the one that throws) is rejected, and then its ancestors. This change was discussed at the July 2025 TC39 meeting. Spec PR: tc39/ecma262#3695 test262: tc39/test262#4591 Differential Revision: https://phabricator.services.mozilla.com/D267210
