Disable sandbox or add an option to toggle
Currently it is no longer possible to do local filesystem web development as access to filesystem has been limited due to sandbox option. This makes GNOME Web in it's current form more or less useless for web developers. We should reconsider the current implementation. Either disable it or at least provide an easy option to toggle the current behaviour.
Sandboxing is also one of the reason why the current pdfjs implementation needs an inline workaround to actually work.
Save as html is therefore also useless as it cannot be viewed anymore.
