Bug#993184: gnome-shell-extension-dashtodock: not compatible with GNOME 40

[Simon McVittie]

Package: gnome-shell-extension-dashtodock
Version: 69-1
Severity: important
Tags: upstream
Forwarded: https://github.com/micheleg/dash-to-dock/pull/1402

The metadata.json for this extension doesn't declare compatibility with
GNOME 40, and it seems the extension code itself is not compatible.

When we do the GNOME 40 transition, hopefully soon, we will have to
either update this extension or remove it from testing. It would be
useful to get a fixed version into experimental.

Thanks,
