Chrome Version: 71.0.3570.0 (Official Build) canary (64-bit)
OS: Mac OSX

What steps will reproduce the problem?
(1) Inspect "chrome://chrome-signin" page (use chrome://inspect).
(2) In console, type: window.open("chrome://chrome-signin");


What is the expected result?
The opened window loads a <webview> to the signin page.

What happens instead?
The new window is grey and empty.

Inspecting the new page shows some JS errors possibly due to missing <webview> API.
