Well, URL is cutted, but there are also no <a href> tags
Well, yeah, because the link generator expects a non-cut URL. It is not 'just' a matter of slapping <a> tags around the field − it’s not super advanced, but there is somme formatting going on [1]
If T112461 is fixed, it should generate link.
No, there are many possible bugs that could prevent link to be generated. T112461 was about a specific one (as stated in the task title, « because of new URL format »), and this one is fixed.
