¿Enlaces de Markdown no funcionan sin https://?

Did something change recently with links?

When you write example.com in a post it automatically works as a link in a post. (meaning it looks like a link and clicking on it takes you to that site).

However when you write

[link](example.com)

link

It looks like a link but there is in fact no link (meaning clicking on it does nothing).

Did this change recently? Someone on our forum noticed that we have a bunch of links like this that are (now?) not working.

NOTE: My example above is when using the Markdown editor (if that wasn’t obvious). When I use the rich wysiwyg editor and just paste example.com in the link dialog box, the link works.
