Expecting hasShadowRoot from global scope

Think hasShadowRoot was added with a debug flag for ```if (CHROME && hasShadowRoot)``` (grepping or acking that should bring you to the culprit). This breaks Chromium builds in Chrome and Electron. For anyone riding the 18 wave; ``` // somehwere above your entry / bundle globalThis.hasShadowRoot = () => true // preload script electron contextBridge.exposeInMainWorld('hasShadowRoot', () => true) ``` To be clear; those are just temporary quick fixes to keep 18 juices flowing. Not recommended for actual use.
