[BUG] Inconsistency for thunderbird

[mseveritt]

Describe the bug
The app icon and the status icon for thunderbird are different.
At least for Cinnamon, for menu and panel, the status icon is used instead of the very beautiful app one.

To Reproduce
Look at Thunderbird icon in menu and panel.

Expected behaviour
The app icon is used for menu and panel.
This could be done by either a removal of the thunderbird icon from status or an alignment of the icons if possible.

Screenshots

Desktop
LMDE 5 Cinnamon 5.2.7, panel height 43, menu icon size 23
