TYPO3 Core

After typing a link like http://www.google.com/ in external tab and clicking on Set Link button, the protocol is getting removed and www.google.com is set in the url field. This works like a charm through ContentObjectRenderer->getTypolink.
Once the url looks like http://www.google.com/whatever.html, www.google.com/whatever.html is being used in the url field. Such link is getting appended to the actual domain and is producing links like http://www.example.com/www.google.com/index.html.

I was able to produce this on Typo3 7.6.1 using DCE TypolinkViewHelper. Only parameter (url) and a subject are passed to getTypolink without further processing.

Might be a case for DCE developers, but still, I wouldn't want to code additional Link handlers just because of that missing http.
