Window is not allowed to navigate Top-frame navigations to data URLs
Deprecations and Removals in Chrome 60:
Remove content-initiated top frame navigations to data URLs
Because of their unfamiliarity to non-technical browser users, we're increasingly seeing the data: scheme being used in spoofing and phishing attacks. To prevent this, we're blocking web pages from loading data: URLs in the top frame. This applies to tags, window.open, window.location and similar mechanisms. The data: scheme will still work for resources loaded by a page.
This feature was deprecated in Chrome 58 and is now removed.
