[Dark Theme Bug Bash] Dark them extra copy button creates extra Copy text

[erdembayar]

Impact

It bothers me. A fix would be nice

Describe the bug

Edge browser

1. Enable dark theme and go to package then press copy
   
2. Paste in Notepad, you'll see extra Copy text, but you wouldn't see it if you do it on nuget.org with the current theme.
   
3. Same bug can repro for all other tabs such as Package Manger, PackageReference etc.

Repro Steps

Edge browser with dark theme https://dev.nugettest.org/packages/e2e.semver2prerel.240506.234617.5383287/ or any other package

Expected Behavior

No extra Copy text in new line besides dotnet add package xxx

Screenshots

No response

Additional Context and logs
