• I completely restarted Steam and checked if the bug is still there
• I have checked if I use the latest version

Describe the Bug!

1. When opening an image sent thought the chat there is no title area so it can't be dragged nor closed.
2. I also assume that it has the wrong colors
   

Expected Behavior

1. Be able to drag the window and close it
2. I guess it should look something like this
   

I used

/* Image popup set correct top bar */
.PopupFullWindow .TitleBar.title-area {
    top: 0;
    width: 100%;
    margin-left: 0;
}

/* Background for the images */
.PopupFullWindow ._1ILFQY2sxyGFT_n-fifayy {
    padding: 31px 10px 10px 10px;
    border: 3px solid rgb(var(--color-5));
    border-radius: 8px;
    background: rgb(var(--color-4));
}

Steps To Reproduce

1. Start a chat with a friend
2. Send an image
3. Open the image
