Start by reproducing the listed warnings in contentScript.js using the reported Brave, Chromium, Linux, and MetaMask versions. Trace ObjectMultiplex handling for the app-init-liveness and background-liveness streams, along with the close and end listeners; done means the reported liveness, malformed-chunk, and MaxListenersExceededWarning messages no longer occur.
