In my experience, when viewing an HTML input field of type "email" with the "multiple" attribute present, Safari shows a blank input, whereas Chrome and FF show the field as expected.
Is this a known bug with Safari? Googling turns up very little for me.
This pen has two inputs, the first is a multiple-email input, the second is just a single value. I expect to see the addresses when viewing the field in Safari, just as I do in Chrome and FF. Instead, it is blank.
<form> <div> <label for="customer_email">A standard multiple-email input field</label><br> <input type="email" size="75" name="customer_email" id="customer_email" value="[email protected],[email protected],[email protected]" placeholder="" multiple> </div> <div> <label for="single_email">A standard single-email input field</label><br> <input type="email" size="75" name="single_email" id="single_email" value="[email protected]" placeholder=""> </div> </form> https://codepen.io/abmg/pen/poBBxOG
Chrome and FF show as expected: 
Whereas Safari shows the multiple input as blank:
