Customizing Additional CSS - Text Unclear

[gsexton]

When you choose Appearance | Customize | Additional CSS, the text box has this:

/*
You can add your own CSS here.

Click the help icon above to learn more.
*/

I sent a user some additional CSS to copy and paste into the box and it came out like this:

/*
You can add your own CSS here.

.Some-Selector {

width: 100%;

}
Click the help icon above to learn more.
*/

This didn't work because the user pasted the CSS inside the comment block, where instructed (here). This should be re-worded to reduce the risk of misinterpretation:

/*
You can customize your site's CSS here. Click the help icon above to learn more.

Enter your custom CSS below this block.
*/

Or some similar message.
