I've found a bug and checked that ...

• ... the problem doesn't occur with the mkdocs or readthedocs themes
• ... the problem persists when all overrides are removed, i.e. custom_dir, extra_javascript and extra_css
• ... the documentation does not mention anything about my problem

Description

When using a fenced pycon codeblock (Python console syntax highlighting) the >>> characters can be skipped of being manually selected using the next custom CSS as is documented in mkdocstrings:

.highlight .gp, .highlight .go { /* Generic.Prompt, Generic.Output */
    user-select: none;
}

But clicking in the "Copy to clipboard button", it copies the whole line, including the >>> part, which is not desirable for pycon code blocks. It seems that ClipboardJS offers a way to edit the content that is copied.

It should be reasonable to add more logic to the clipboard component? Maybe checking the CSS of the text and skipping all the content styled with user-select: none;? Thanks in advance!

Expected behaviour

Copying pycon fenced code blocks should not include >>> Python console characters.

Actual behaviour

Undesired characters are copied.
