The report does not identify a source file, test, platform, Cordova configuration, or reproduction project. Start by collecting the missing plugin list, package versions, OS details, logs, and a minimal reproduction, then trace the `targets[0].offsetHeight` access. Done means the failure is reproducible and its correction is verified.
