Testcase Gist URL

https://gist.github.com/jmercouris/5682e62e11b73c8b2e99c303d51eacd0

Additional Information

If you change the URL for both URLs to something like:

a:asdf

and

b:sdf

it will work.

[jmercouris]

If setting the scheme privileges to standard is supposed to elicit this behavior, I believe it should be more clearly documented.

[dsanders11]

@jmercouris, this is expected behavior. You're registering the scheme as standard and then trying to load a URI which does not conform to the expected syntax. From the docs:

A standard scheme adheres to what RFC 3986 calls generic URI syntax. For example http and https are standard schemes, while file is not.

If you change the URl to a://foobar, which adheres to the generic URI syntax, it works fine.

[jmercouris]

However, it isn't documented clearly. I think it could be more thoroughly explained.
