the backdrop is not work through css variable, but it works well through the certain value. and the problem wasn't appear in old version

Safari throw a ViewTransition error, called ' Unhandled Promise Rejection: AbortError: Old view transition aborted by new view transition.' however, i don't find how to catch it. i used 'try..catch' or Promise.catch, or catch it in finished/ready/updateCallbackDone Promise. These all don't work.
