Html tags showing instead of link in JobItemForm

The code seems fine and it works fine.
I'm providing an snapshot of the result:

This seems more complicated than it has to be. Instead of creating two arrays and merging them, why don't you just move the if/else below and just set the additional key in there? At that point, it might be simple enough to do it as a ternary?

The patch looks good but I tested locally and some links are not working.
You should also fix the link in.

 $message = 'The translation for @source has been accepted.';
 $variables = array('@source' => $url ? \Drupal::l($this->getSourceLabel(), $url) : $this->getSourceLabel());

and add some test for that.

Now looks good! but we need tests.

If it needs tests, should go to needs work.

There is a tabulation that should not be there, but this issue fixes the head, and as it passes the tests and the code seems fine.
I set it to RTBC, as should be commited asap and maybe delete the tabulation on commiting.

Ok it seems that the head is fixed.

Great, committed.
