Subject: [PATCH] Add support for NO_TITLE in vue, disabling border (#7589)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When `node.title_mode` is set to `TitleMode.NO_TITLE` the node header is
not displayed in vue mode.
| Before | After |
| ------ | ----- |
| <img width="360" alt="before"

src="https://github.com/user-attachments/assets/34ea3a28-cc2e-4316-a154-40f54bdf8e60"
/>|

When a node has specified both `NO_TITLE` and a transparent background,
node borders are also disabled in vue mode.

Known issues:
- `NODE_TITLE_HEIGHT` strikes again.
