Here's a draft you can paste directly into the GitHub issue:

Title: Cannot selectively copy text from assistant response — only full-message copy works

Description:

In Claude Code on the web, it is not possible to select and copy a specific portion of text from an assistant response. Attempting to click-drag to highlight a substring results in either no selection or the entire message being selected/copied instead.

Environment:

• Claude Code: Web (remote execution / cloud session)
• Platform: Browser

Steps to reproduce:

1. Receive any multi-line response from the assistant in the Claude Code web interface
2. Attempt to click and drag to highlight a specific word, sentence, or paragraph within the response
3. Press Ctrl+C / Cmd+C to copy

Expected behavior: The highlighted/selected text is copied to the clipboard.

Actual behavior: Either the selection does not work as expected, or only the full message is copied rather than the selected portion.

Impact: This makes it difficult to extract specific code snippets, URLs, or sections of a response without copying and then manually trimming the entire message text.
