@sepple , the team reviewed the suggested change to the code and unfortunately we rejected your contribution. Below is the response from the team in details:

This is currently working as expected. If the recommended change is made as explained, the end result would be invalid html being produced for the dob.phtml template. Two extra / will be introduced following the closing div tags.
Here is a sample of what is expected:

<div><label for="month"><span>M</span></label><input type="text" id="month" name="Month" value="jan"></div>
<div><label for="day"><span>d</span></label><input type="text" id="day" name="Day" value="1"></div>
<div><label for="year"><span>yy</span></label><input type="text" id="year" name="Year" value="14"></div>

And here is the result with the suggested change: (Notice the extra and invalid / following the tags.)

<div><label for="month"><span>M</span></label><input type="text" id="month" name="Month" value="jan"></div>/
<div><label for="day"><span>d</span></label><input type="text" id="day" name="Day" value="1"></div>/
<div><label for="year"><span>yy</span></label><input type="text" id="year" name="Year" value="14"></div>

Well you are right, I was working in my own theme where it was all inline elements, replaced the div with span elements. The problem seems to be bigger now. The Block class is linked to the template file using block layout style. If I want to keep the date format as is, I run into problems.
I will post a new request with a better change than I suggested here.
