In the URL Bar missing http is a feature. But when I copy and paste a link and no http:// appears in the link then is it a bug? or something like any feature of the Google DOC.
If your requierements say "When copying an URL from address bar there must be
http:// in the link" then it's a bug.
If your requierements say "When copying an URL from address bar there must not be
http:// in the link" then it's not a bug.
If your requierements say nothing about
http:// in the copied link, then why do you test it?
Have your tried copy URL of this page from address bar?
You will see that on copying and then pasting, it will append HTTP. By default, browser takes HTTP and don't displays it.
In case, its HTTPS you can see HTTPS specifically appearing in address bar.
As of now, I can't see any site which on copying pasting is not showing HTTP/HTTPs.
Please re-check the link you are trying.
