Platform / OS version: MacOS 10.14.3

What steps will reproduce the problem?

What happens instead?

shows a blank screen: ndb-start

inspecting the window, I see errors in the console: ndb-console-error

ndb_app.js:3 Uncaught TypeError: document.registerElement is not a function
    at Object.UI.registerCustomElement (ndb_app.js:3)
    at ndb_app.js:3
    at ndb_app.js:3

no errors in the terminal (when invoking ndb)

I’ve also tried with:

Perhaps carlo changed how it launches Chrome during those releases.

But, I’ve just tried it again and the latest Canary 74.0.3726.0 works.

I wonder if it would be better to be able to select the browser we want to use with ndb. Maybe having the chance to change what chrome is used would simplify how we troubleshoot 🤔

Looks like this is due to Shadow DOM v0 being removed - https://www.chromestatus.com/features/4507242028072960. Either a polyfill will have to be added or update to the shipping standard.
