The length of scheme is at least five characters even when the scheme has 'web+' prefix

The length of scheme is at least five characters even when the scheme has 'web+' prefix

The content-scheme handler specification requires that it is SecurityError if the length of
scheme isn't five characters at least, including 'web+' prefix. Thus, we need to check the length
of scheme on the 'web+' scheme.

The latest specification requires that it is a SecurityError if the length of
scheme isn't at least five characters.(including 'web+' prefix). So, we need to
check the length on 'web+' scheme.

An extract from the specification.

If the registerProtocolHandler() method is invoked with a scheme that is neither
a whitelisted scheme nor a scheme whose value starts with the substring "web+"
and otherwise contains only lowercase ASCII letters, and whose length is at
least five characters (including the "web+" prefix), the user agent must throw a
SecurityError exception.
