@resource don't support SSRI

According to the documentation, the @resource should be look like follows:

// @resource icon1 http://www.tampermonkey.net/favicon.ico
// @resource icon2 /images/icon.png
// @resource html http://www.tampermonkey.net/index.html
// @resource xml http://www.tampermonkey.net/crx/tampermonkey.xml
// @resource SRIsecured1 http://www.tampermonkey.net/favicon.ico#md5=123434...
// @resource SRIsecured2 http://www.tampermonkey.net/favicon.ico#md5=123434...;sha256=234234...

But after enable SSRI and the @resource get TypeError [ERR_INVALID_URL].
