VS Code

Body

When attaching images in VS Code Copilot chat (either via the attachment button or Ctrl+V paste), the image appears visible in the chat input but the model receives an empty tag with no content. The image is never transmitted.

Steps to reproduce:

Open Copilot chat in VS Code (Insiders, version [your version])
Paste an image with Ctrl+V or attach via the paperclip button
The image appears in the chat input as a thumbnail
Send the message
Model responds as if no attachment was provided
Expected: Model receives and can analyze the image

Actual: Model receives empty tag — confirmed by the model explicitly stating no image data is present

Additional context:

Reproduced across multiple images, multiple attempts, after VS Code update, and across multiple models (Claude Sonnet 4.6, others)
The image file is saved locally at C:\Users...\AppData\Roaming\Code - Insiders\User\workspaceStorage\vscode-chat-images\ — the file exists, it just isn't passed through
