Registration Form Step 47 may be broken in Safari

[bbsmooth]

Describe the Issue

I've come across two forum posts from Safari users in the past few days saying that they can't pass step 47 even though their CSS is correct.

Based on the hint they are getting, the test that is not passing is:

assert(borderBottom === 'none' || borderBottom === 'medium none');

I'm wondering if Safari has recently changed the string being returned for the border properties when set to none? I don't have a mac so I can't test this for myself. Opening this issue with the hopes that a Safari user can figure out what is going on here. Should be tested on a very recent version of Safari.

Your code

fieldset:last-of-type { 
  border-bottom: none;
}

This is the correct CSS but it is apparently not passing for Safari users.

Expected behavior

Correct CSS should pass.
