[Bug] Frame title persists in output after deletion in Excalidraw VS Code Extension

[hoelzleva]

When deleting a Frame created using the Frame tool in the Excalidraw VS Code extension, the frame's title remains visible in the generated output file (e.g., SVG), even though it is no longer visible or editable in the editor. This leads to inconsistencies between the editor view and the exported file, and the leftover title cannot be modified or removed from within the editor. Issue persists even when resetting the canvas or "undo" action.

Steps to Reproduce:

1. Create a new file (e.g., test.excalidraw.svg) in VS Code.
2. Use the Frame tool to draw a Frame.
3. Delete the Frame.
4. Save the file.
5. Open the saved file in a browser.

Expected Result: The frame and its title should be completely removed from both the editor and the output file.

Actual Result: The frame title remains visible in the output file but is no longer visible or editable in the VS Code editor.

Workaround: Delete the title in the SVG code

Excalidraw extension version: 3.9.0
