Rich text copy from Copilot Chat converts file links to non-functional vscode:// URIs

[AdrienFelipe]

Problem

When copying text from the Copilot Chat panel using rich text copy (default behavior), file references that the agent formats as workspace-relative markdown links (e.g., [src/file.ts](src/file.ts#L10)) get converted to vscode://file/... URIs in the clipboard HTML.

These vscode:// links don't work when pasted into:

• Azure DevOps wikis/work items
• Microsoft Teams
• Outlook emails
• Confluence/Notion/other documentation tools
• Any context outside VS Code

Expected behavior

When rich-copying from Chat, file links should be converted to either:

1. OS file paths (e.g., C:\src\project\src\file.ts) — universally understandable
2. Workspace-relative paths as plain text (e.g., src/file.ts:10) — portable and readable
3. Or at minimum, the vscode:// scheme should be a clickable protocol handler that actually opens the file when clicked from outside VS Code

Current workaround

Setting "chat.richTextCopy.enabled": false gives plain markdown, but loses all formatting (headers, bold, code blocks, tables).

Reproduction

1. Open VS Code with Copilot Chat
2. Ask Copilot a question that references files in your workspace (e.g., "explain this file")
3. Copilot responds with clickable file links in the chat panel
4. Select the response text and copy (Ctrl+C)
5. Paste into any external tool (Teams, ADO, Outlook, Notion, etc.)
6. File links appear as vscode://file/... URIs that don't resolve

Environment

• VS Code: 1.99+
• OS: Windows 11
• Copilot Chat: built-in (GitHub Copilot extension)

This may be fixed by PR #328466 as I noted there.
