Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

Clicking the Copy button in the top-right corner of CodeBlock and then pasting it into any editor loses the indentation.

I tried adding src\theme\CodeBlock\Buttons\CopyButton\index.tsx.
And replacing import copy from 'copy-text-to-clipboard'; with navigator.clipboard.writeText(text).catch(console.error);.
Then copying works fine.

Reproducible demo

No response

Steps to reproduce

I didn't try to create a new repository for testing. It just happened to multiple people in my repository.

Expected behavior

The contents of the code block should be copied as is.

Actual behavior

At present, the original content will actually be modified. I don’t know what operation or replacement was done, which resulted in the loss of indented content.
