Preconditions

Steps to reproduce

1. Go to Stores -> Configuration -> Sales -> Sales under Gift Options and set both Allow Gift Messages to YES
2. Put something in cart and go to checkout or cart page

Expected result

1. Two forms for gift messages having fields with unique ids

Actual result

1. Two forms for gift messages having fields with non unique ids

[DOM] Found 2 elements with non-unique id #gift-message-whole-from: (More info: https://goo.gl/9p2vKq) <input type=​"text" id=​"gift-message-whole-from" class=​"input-text" data-bind=​"value:​ getObservable('sender')​">​ <input type=​"text" id=​"gift-message-whole-from" class=​"input-text" data-bind=​"value:​ getObservable('sender')​">

@angelo983 did you got any solution for this ? I am getting this error in Magento 2.1.8 even when both Allow Gift Messages are set to No

Hi @EmilyPepperman I've this similar issue: (in checkout page)

[DOM] Found 2 elements with non-unique id #send2: (More info: https://goo.gl/9p2vKq [^])
<button type=?"submit" class=?"action action-login secondary" name=?"send" id=?"send2">?…?</button>?

Anyone has experienced same situation?
