If someone told the young Linux freak me back in the early 2000s that one day Internet Explorer’s rendering engine is based on the KDE rendering engine I would’ve probably died laughing and frozen in horror at the same time. Yeah, I realize there’s probably nothing left if the old KHTML but it still does give me a chuckle.
There's still plenty of references and small but essential stuff. One notorious example that comes to mind is the KURL name that stuck: https://chromium.googlesource.com/chromium/blink.git/+/maste...
Although, all copyrights are Apple's on that particular file. I wonder if everything's been done by the book.
