Thunderbird icon missing in panel of Cinnamon

[nany]

Hello,

In Ubuntu Cinnamon 24.04, the icon of Thunderbird doesn’t appear in the panel.

I had to copy the icon from /snap/thunderbird/current/snap/gui/ to /usr/share/icons/hicolor/48x48/apps/ to show it.

Dist-upgrade from early release of 22.04 to 23.10 then to 24.04.
Thunderbird DEB package replaced by SNAP package in the process.
If I search for Thunderbird and pin it, then there's an icon in Grouped Window List. If I click the icon, it opens new window without an Icon in the Grouped Window List. If I pin the new no-icon window, then it leaves a small gap between other pinned icons/windows.

What logs or information do you need to investigate further?

Ooo, interesting. If I use the `Papirus` icon theme, then thunderbird gets its icon.
