Hex code of background-color is not displayed by Edge

Question

I use the following simple HTML and CSS code:

.content {
  background-color: #e9ddafff;
}

<div class="content">
Content goes here.
</div>

This code works perfectly in all browsers except for Edge. When you open it in Edge the browser does not recognize the background-color. I guess somehow Edge cannot deal with the hex code #e9ddafff because when I change it to red everything works.

Do you have any idea what I need to change in my code to also make it work in the Edge browser?
