Open DevTools on a new tab page (I guess this has something to do with service worker).
Click on Global Event Listeners in Sources sidebar.

The list is empty, got the following exception:
"Uncaught (in promise) TypeError: Cannot read property 'script' of null", source: chrome-devtools://devtools/bundled/sdk/RuntimeModel.js (697)

Version: developer build 886eadcb2ee08f462586e3281c4b682774884e36-refs/heads/master@{#462582}
Not sure whether this happens in M58.
