Describe the bug

GitHub Copilot's built-in voice dictation does not recognize the inline comment editor in the Changes canvas as a text box, even when the editor is open and focused.

Starting built-in dictation produces an Error details dialog:

Use a text box
Voice dictation types into whichever text box you've selected. Open a workspace
or click in a text field, then try again.

The inline comment editor remains visible and focused behind the dialog. No dictated text is inserted.

This is distinct from #3770, which reports Windows Win+H voice typing in the CLI prompt. This report concerns Copilot's built-in voice dictation in the desktop app's Changes canvas.

Affected version

1.0.87-0

The same behavior was also observed on a slightly earlier app version.

Steps to reproduce the behavior

1. On Windows, open a project session that has file changes.
2. Open the Changes canvas.
3. Select a changed line and open its inline comment editor.
4. Click inside the comment editor so it is visibly focused.
5. Start GitHub Copilot's built-in voice dictation.
6. Observe the Use a text box error instead of dictated text appearing in the comment.

Expected behavior

Built-in voice dictation should recognize the focused Changes inline comment editor as an editable text field and insert the transcript at the cursor.

Additional context

• Platform: Windows, 64-bit, OS build 26220
• Current Copilot version: 1.0.87-0
• Reproduces consistently on the current version.
• The error suggests the dictation focus/target detection does not classify the Changes inline comment editor as a supported text input.
• Public issue search found no report specific to built-in dictation in Changes inline comments.

Closing because this was filed in the wrong repository. The exact app bug is already tracked in github/app#4044. Current Windows reproduction details and the screenshot have been added there.
