I've registered the custom scheme "string" and I'm using a custom ResourceHandler to handle resources prefixed with "string://" so that I can display simple messages in the browser without having to load a file.

When attempting to set the URL to something like "string://Hello" it works fine; it enters my resource handler and displays "Hello".

But as soon as I introduce spaces to the URL (plain spaces, encoded as + or %20, as part of a querystring parameter or at the front of the uri) I get "The Page Failed to Load..." and it never gets into my custom ResourceHandler.

Some examples that don't work:
string://Hello World
string://Hello+World
string://Hello%20World
string:x?x=Hello World
string:x?x=Hello+World
string:x?x=Hello%20World

Hi,

This seems to be a timing issue. We were able to reproduce it a few times but not consistently. We will continue to investigate and post again if we find anything.

Thanks!
