autostart is forced on

```Dropbox daemon version: 238.4.6305```
```Dropbox command-line interface version: 2025.05.20```

Once the app is started it overwrites one's preference that it does not start at boot.

In ```gnome-startup-applications``` one has unticked Dropbox, which is functionally the same as adding ```X-GNOME-Autostart-enabled=false``` to ```~/config/autostart/dropbox.desktop```.

One has run ```dropbox autostart n```. This has no effect on the dropbox.desktop.

Someone seems to have reported it in August - [v230.4.8797](https://askubuntu.com/a/1554838)

Start by reproducing the behavior with `dropbox autostart n` and inspect the generated `~/config/autostart/dropbox.desktop`, including `X-GNOME-Autostart-enabled=false`. Trace where the Dropbox desktop entry is created or updated and compare it with the GNOME startup setting. Done means disabling autostart persists after starting the app and the desktop entry remains disabled.
