Currently these types of loads are blocked but they might be needed by some sites. The spec doesn't really say whether they are in scope or not.

data: URLs are needed by DomTerm. For example domterm hcatof an image works by converting the image to base64 and sending a data URL.

DomTerm could perhaps work around the lack of data URLs but it would be a major pain.

Does it load these data URLs as a toplevel URL?

"Does it load these data URLs as a toplevel URL?"

No, I can't see any need for that. It would be mainly for images.

Then you're fine irrespective of our decision here. We're not disabling all of data: URLs; this is only about whether they and blob URLs can be loaded as toplevel documents inside the site-specific browser. You could imagine, say, a link in example.com that points to data:text/html,<a href="https://example.com/">Back</a> [more content here], and in theory that might "work", if we allowed it. It's not clear whether we should.

Thanks. I see you changed the title to make that clear.

(DomTerm catches clicking on links anyway, redirecting them to a regular browser window/tab.)
