Description Kate Cheney 2020-09-18 14:37:08 PDT 
In the original implementation of App Bound Domains, any loads using certain protocols like about: were automatically considered app-bound. When a subframe loads about:blank for example, this forces web views into app-bound mode even if the top frame is not app-bound. An idea is to refer to the security origin of the top frame in this case to determine if a subframe should be considered app-bound.
