I just wanted to make an observation on this topic because I saw the change with the new v20 version.

In CSS you should your position: absolute then you can arrange the icon into the right position. This is a test for the email icon

.icon-copy {
    display: inline-block;
    background-image: url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 111.07 122.88"><path d="M97.67 20.81h0l.01.02a13.38 13.38 0 0 1 9.46 3.93 13.32 13.32 0 0 1 3.9 9.42h.02v.02 75.28.01h-.02c-.01 3.68-1.51 7.03-3.93 9.46a13.32 13.32 0 0 1-9.42 3.9v.02h-.02-59.19-.01v-.02c-3.69-.01-7.04-1.5-9.46-3.93a13.37 13.37 0 0 1-3.91-9.42h0V34.2v-.01h.02c.01-3.69 1.52-7.04 3.94-9.46 2.41-2.4 5.73-3.9 9.42-3.91v-.02h.02l59.17.01h0zM.02 75.38L0 13.39v-.01h.02a13.44 13.44 0 0 1 3.93-9.46A13.37 13.37 0 0 1 13.37.01V0h.02 59.19c7.69 0 8.9 9.96.01 10.16H13.4h-.02v-.02c-.88 0-1.68.37-2.27.97-.59.58-.96 1.4-.96 2.27h.02v.01 3.17 58.81c0 8.26-10.15 8.72-10.15.01h0zm100.89 34.11V34.2v-.02h.02c0-.87-.37-1.68-.97-2.27-.59-.58-1.4-.96-2.28-.96v.02h-.01-59.19-.02v-.02c-.88 0-1.68.38-2.27.97-.59.58-.96 1.4-.96 2.27h.02v.01 75.28.02h-.02c0 .88.38 1.68.97 2.27s1.4.96 2.27.96v-.02h.01 59.19.02v.02c.87 0 1.68-.38 2.27-.97.59-.58.96-1.4.96-2.27h-.01 0 0 0z" fill-rule="evenodd"/></svg>');
    background-repeat: no-repeat;
    background-size: contain;
    cursor: pointer;
    width: 12px;
    height: 12px;
    margin: 3px 0 0 6px;
    position: absolute;

and the same width, height and margin for the order icon. In this way both icons will look good. The color for the order must be the same with text. For the email it should be evaluate orange from the email or black from the text.

@ADDISON74 I would not recommend using position: absolute, especially without any relative container outside.
Your proposed color changes are already part of this PR 🙂

But having a closer look at the copy code button implementation, I would improve the following:

• span should be a button
• the data attribute should not be the only selector but rather a css class in addition
• onclick should be an event listener
• code is not admin related, so it should be in a more general JS file in js/mage

I've tested your PR and it's needed so I'll merge it right away.

Personally I'd still keep the code in a "admin" related file but further improvements can be done for sure in a separate PR.
