Since about a week ago, both the source editor and VisualEditor force the creation of piped links when using the built-in hyperlink feature if the text is the same as the link AND the article has spaces in its title AND the text to be linked begins with a lowercase character.
Before, linking "five-year survival rate" or "short bowel syndrome" would result in "[[five-year survival rate]]" or "[[short bowel syndrome]]".
Now, it results in "[[Five-year survival rate|five-year survival rate]]" and "[[Short bowel syndrome|short bowel syndrome]]" every time.
