No "Copy To Clipboard" Icon on Code Blocks

[nixliuxin]

Hi, after configuring the mkdocs.yml as follows, there is still no "Copy To Clipboard" icon on the code blocks. How can I add this function? Thanks!

The copy to clipboard functionality mounts automatically, no configuration necessary. There's likely an error in your configuration, which results in an error in the browser's console, leading to the copy-to-clipboard button not being mounted. If you spin up a new instance of Material for MkDocs, you'll see that the button works nicely. Try removing your customizations (also extra JS and CSS), and if the error persists, narrow it down to a minimal reproducible example which you attach here as a zip.

Thanks for your reply. I notice that disabling the built-in privacy plugin can solve the problem, but this doesn't allow me to get a local copy of assets such as custom font files. Are there any hints to solve the issue?

As said, please provide a minimal reproduction and attach it here as a zip.

Don't want to hijack this topic (Let me know if you want me to open a new issue)
But i noticed the same issue on my page.
After some testing when i switch back to mkdocs-material==8.5.11 it works and shows the copy to clipboard icon

mkdocs-material==8.5.11

mkdocs-material==9.0.3/mkdocs-material==9.0.5

Seems the issue is because if a change the changelog i missed

Sorry for noise and panic for nothing
