Copy code block icon no longer appearing

• I’ve read the contribution guidelines and agree with them

I’ve found a bug and checked that …

• … the problem doesn’t occur with the default MkDocs template
• … the problem is not in any of my customizations (CSS, JS, template)
• … the documentation does not mention anything about my problem
• … there are no open or closed issues that are related to my problem

Description

The updated Material theme (I am using insiders) no longer allows the user to copy code blocks with the click of a button. To test I created a new project and updated my mkdocs.yaml with the plugins/extensions I am using.

When hovering over the code block there is normally an icon for the user to click on to copy the code block. With the updated version this does not appear.

Expected behavior

Icon to copy the code block text should appear when hovering over the code block.

Actual behavior

The icon to copy the code block does not appear.

Steps to reproduce the bug

1. Create a new project
2. Add plugins/extensions to yaml
3. Update index.md to have a simple code block
4. Hover over the code block, the copy icon does not appear

Confirmed that following the directions under the localsearch project fixed the issue. Thank you! https://github.com/wilhelmer/mkdocs-localsearch

Argh I am kicking myself, I saw that part of the upgrade guide but it didn’t dawn on me that it would impact me in that way. My apologies, making the update now and will confirm.
