And, I'll see if I can find a workaround for you.
For now, install https://chrome.google.com/webstore/detail/copy-page-url/dobnehimlklapeengfdlhdkpijhjdkag in Opera. Then, you can just right-click the page and choose "Copy page URL" instead of copying from the address field. Then, you'll get a URI like you want instead of an IRI.
I'll try,thanks a lot.
