Chrome: 69 and newer
OS: Window 7 and Linux, probably all

===========================

Repro: 
1. enable chrome://flags/#enable-layout-ng and restart Chrome
2. open the attached test.html
Expected: an "external site" icon is shown - a box with an arrow pointing outside
Observed: a filled rectangle is shown

===========================

Bisected to r572466 "[LayoutNG] Add a chrome:://flags for LayoutNG"
Can't bisect earlier builds since it would require building Chromium.
