When importing @sentry/browser from a service worker file (e.g: background.js) like

import * as Sentry from '@sentry/browser';

we get

Uncaught TypeError: Cannot read properties of undefined (reading 'visibilityState')

var initHiddenTime = () => {
  return (0,_sentry_utils__WEBPACK_IMPORTED_MODULE_0__.getGlobalObject)().document.visibilityState === 'hidden' ? 0 : Infinity;
};

It crashes at the import level, because @sentry/browser relies on the document which doesn't exist in the context of a background script.

Edit: That's because I was loading BrowserTracing, when removing it it doesn't crash!
