The "copy to clipboard" icon seems broken in the new theme #710
Description
Describe the bug
It seems like the "Copy to clipboard" icon is not showing up properly. Instead, there is a long text that says "Copy to clipboard"
Expected behavior
I think it should show the copy icon instead of the text.
